== vertical ==
What about mixing top/bottom and l/r or r/l on the same page?  Somewhere, I think I remember reading something about this... does anyone know the details?

: CJK are the only languages I know that can be written vertically.  CJK are traditionally written in columns from right to left. This vertical writing is not a requirement, so they are often display horizontally from left to right.  
: When you purchase CJK fonts, most fonts come w/a vertical variation (name of the vertical variation would start with @ symbol).  They are the same glyphs but rotated 90 degrees counterclockwise.  It is not meant to be read on screen, because you will have to tilt your head 90 degrees to read it.  These rotated fonts are for printing.  When you print, the text will come out vertically.  
: I know there are better implimentation of this in CSS for screen display, but I haven't seen any site using it except for demonstartion. --[[User:Voidvector|Voidvector]] 08:40, Nov 23, 2004 (UTC)

== What tools Wiki provide for bi-directional text ? ==

I am very interested to know what tools are there for making the edit pages bi-directional. That is to provide a facility in the form of a button, so the user can choose which direction he/she is going to write.  Any one knows where or how this can be done? [[User:Mehrdadd|Mehrdad]] 03:29, 5 May 2006 (UTC)

: As far as I know, bi-directional support is handled by the browser (client-side), not wiki server (server-side). If your browser supports bi-directional text, then the text would be displayed correctly, otherwise, no luck.--[[User:Voidvector|Voidvector]] 19:29, 6 July 2007 (UTC)

:: The statement about the Hebrew text rendering wrong in some browsers seems like incorrect "Original Research" to me.  The ordering issue isn't about characters, but text orientation and text within controls.  ABC encapsulated in P tags isn't going to render CBA, but is it [ABC  ] or [  ABC].  Whether it is CBA is about whether or not you typed CBA or ABC.  Secondly within input boxes and others it is about whether when I hit A it goes: [A     ] or [     A] and when I hit B does it go [AB    ] or [    BA].

=="Bidi" as printing term==

This article mentions the term 'bidi' for bidirectional (of texts that include multiple scripts written in more than one direction). It is also (perhaps only historically now) a term for e.g. dot-matrix printers that can print more quickly by placing ink onto the page whichever way the print head is moving (i.e. not just printing left to right and then "inklessly" moving back to the left-hand side). Since "bidi" redirects here, should there be some sort of disambiguation page dealing with this sense?  <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/86.131.102.65|86.131.102.65]] ([[User talk:86.131.102.65|talk]]) 21:38, 13 November 2007 (UTC)</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

== Unicode logical store vs presentational rendering ==

The article says, "In Unicode encoding, all non-punctuation characters are stored in writing order." This is not true: text in the Indic ranges is stored in pronunciation order, with the rendering system responsible for rearranging glyphs as the orthography demands.

[http://www.unicode.org/versions/Unicode4.0.0/ch09.pdf Section 9.1 of the Unicode Standard 4.0] says:

<blockquote>
The orthographic syllable is built up of alphabetic pieces, the actual letters of the Devanagari script. These pieces consist of three distinct character types: consonant letters, independent vowels, and dependent vowel signs. In a text sequence, these characters are stored in logical (phonetic) order.
<br>(page 220)
</blockquote>

<blockquote>
Additionally, a few Devanagari characters cause a change in the order of the displayed characters. This reordering is not commonly seen in non-Indic scripts and occurs independently of any bidirectional character reordering that might be required.
<br>(page 220)
</blockquote>

<blockquote>
The greatest variation among different Indic scripts is found in the way that the dependent vowels are applied to base letterforms. Devanagari has a collection of nonspacing dependent vowel signs that may appear above or below a consonant letter, as well as spacing dependent vowel signs that may occur to the right or to the left of a consonant letter or consonant cluster. Other Indic scripts generally have one or more of these forms, but what is a nonspacing mark in one script may be a spacing mark in another. Also, some of the Indic scripts have single dependent vowels that are indicated by two or more glyph components—and those glyph components may ''surround'' a consonant letter both to the left and right or may occur both above and below it.
<br>The Devanagari script has only one character denoting a left-side dependent vowel sign: U+093F DEVANAGARI VOWEL SIGN I. Other Indic scripts either have no such vowel signs (Telugu and Kannada) or include as many as three of these signs (Bengali, Tamil, and Malayalam).
<br>(page 220)
</blockquote>

<blockquote>
Because Devanagari and other Indic scripts have some dependent vowels that must be depicted to the left side of their consonant letter, the software that renders the Indic scripts must be able to reorder elements in mapping from the logical (character) store to the presentational (glyph) rendering. For example, if '''C<sub>''n''</sub>''' denotes the nominal form of consonant '''C''', and '''V<sub>''vs''</sub>''' denotes a left-side dependent vowel sign form of vowel '''V''', then a reordering of glyphs with respect to encoded characters occurs as just shown.
<br>(page 228)
</blockquote>

Anyone want to edit the article to allow for the above without straying from the scope of the article? [[User:Dcamp314|Christian Campbell]] ([[User talk:Dcamp314|talk]]) 01:57, 30 November 2007 (UTC)

: The Internet meme thing is possibly of relevance to articles on [[Internet meme|internet memes]] or possibly some modernization of ASCII_Art#Unicode.  It just isn't of great relevance to an article about bidirection text.  It depends on how widespread it is.  (Which I cannot say).  I can say with great authority it is not in at least 99.99999% of all bidirection text printed or electronic.  Therefore it is irrelevant to this article on both policy and logical grounds.  There really should be a master article on electronic text art and references to unicode art and ascii art and ebdic art or whatever and links down from there.

== Strong vs Weak characters ==

The article confuses 'weak' (numbers, mainly) with 'neutral' (punctuation and symbols) characters. The specification is here: http://unicode.org/reports/tr9/

Weak characters are sequenced together, but don't affect neutrals and can be embedded in runs of strong characters without breaking those runs. Neutral characters are sequenced within runs according to the direction of that run, or by the overall document order when they sit on the edge of a run.

== Unicode for "TM" seems wrong ==

The Unicode U+8482 for symbol <sup>TM</sup> as mentioned seems wrong.

I convert it to decimal (3392), and use "&#3392 ;" in a html file, then it display an unknow symbol (ീ) in my browser.

AFAIK, both U+E150 and U+E143 are for <sup>TM</sup> symbol.

For example, H E150 == D 57680, and "&#57680 ;" display as: .--[[User:Lovelywcm|Lovelywcm]] ([[User talk:Lovelywcm|talk]]) 00:09, 3 June 2008 (UTC)

:8482 is the correct '''decimal''' code for <sup>TM</sup>, hexa being 2122. E143 and E150 are in a 'private use' section, meaning that there is no guarantee that these would display this sign in all situation. [[User:Clpda|Clpda]] ([[User talk:Clpda|talk]]) 20:02, 12 September 2008 (UTC)

== Top-Heavy article ==

This article is quite good in terms of content. Thank you to all those involved in writing it. But it is a bit top-heavy. Most of the content is in the introductory paragraph, ''before'' the table of contents. The opposite should be true. Introductory sections are important, for example for mobile platforms such as cell phones and [[PDA]]s where the rest of the article might not be loaded until explicitly requested. But they should be a few paragraph long rather than an entire screen. May I recommend then to summarize the current content into a couple of paragraphs and move the rest under the Table of Content, possibly breaking it down in a couple of subsections? -- [[User:Manu3d|manu3d]] ([[User talk:Manu3d|talk]]) 12:08, 17 September 2008 (UTC)

== Eastern Arabic Numerals ==

Editor BIL added the line, ''[[Eastern Arabic numerals]] are written left-to-right, and if they are considered part of Arabic script, then Arabic script can written in both directions.'' The problem with this statement is the hidden Western bias in assuming that numbers written in the decimal system are "properly" read from the element with the highest order of magnitude to the one with the lowest. There's no particular mathematical reason for this convention, and in fact the linked article on Eastern Arabic numerals explicitly states, ''Numbers are traditionally read with the smallest element first (e.g., "four-and-twenty" instead of "twenty-four"). Written numerals are arranged with their lowest-value digit to the right, with higher value positions added to the left. This is identical to the arrangement used by Western texts using Western Arabic numerals, even though Arabic script is read from right to left.'' Thus this is not an example of bidirectional text, and I have accordingly removed it from the article. [[User:JudahH|JudahH]] ([[User talk:JudahH|talk]]) 14:18, 14 March 2012 (UTC)
:One can ''read'' (''speak'') "four-and-twenty", and still ''write'' "24" (in Eastern Arabic: {{lro}}&#x0662;&#x0664;{{popdf}}, correct?). In bidi text, the writing is what it is about. So, since the numeric value "24" is written &rarr;"24" or &rarr;"{{lro}}&#x0662;&#x0664;{{popdf}}", (presenting the numeric decimal value 24), it is a L-to-R direction. In surrounding Arabic regular text (R-to-L), this an alteration, and therefor is ''bi''-directional writing. The text could be back in then. -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 23:39, 14 March 2012 (UTC)
::What makes you say that the numeric value "24" is written &rarr;"24"? Is there something about the number that implies an order? Using "24" to denote "two tens and four ones" (or "four ones and two tens") implies a correlation between "left/right" and "larger order of magnitude/smaller order of magnitude"; neither of these inherently implies anything about "first/second". [[User:JudahH|JudahH]] ([[User talk:JudahH|talk]]) 00:59, 15 March 2012 (UTC)
:::Since we are talking EA numerals, well that is what the article (and its picture) says: "Written numerals are arranged with their lowest-value digit to the right" (i.e. the four in 24). So, it is the decimal-radix system we know well, only the individual digit faces (glyphs) are changed: 2=&#x0662;. From there on: of course within a decimal number the order is important. It says which is the tenners (2) and the one'rs (4). The counted value of "24 sheep" would change if it is reversed. In Unicode this is shown by the character properties "Numeric type" and "numeric value", which is "Decimal" and "2" in both examples. (If it were a fancy numerical system like Roman Numerals, they would not be "Decimal"). So far about the numbering system.
:::Now there ''could'' be a EA numbers writing rule that says: "write the sequence R-to-L" to describe our 24 sheep: {{rlo}}&#x0662;&#x0664;{{popdf}}&larr;. If this rule  exists, I would be wrong: because then between Arabic text the number does ''not'' change diretionality of the text, the whole would be single-directonality. I have not found this rule, and the article doesn'says different.
:::Now there is one big confusing aspect that makes bidi writing so difficult to understand: it is not about the "speaking direction". That does not exist: a radio transmitting say in Arabic and then in German will produce one single "direction" (time sequence): second 1 to 2 to 10 for each language. Even browser technology uses, confusingly, "Arabic language" to get a R-to-L effect, instead of "Arabic script". To add to this confusion ;-) Your example of spoken language translates nicely into German: "Es gibs vier-und-zwanzig (24) Schafe". So the pronounciation says "four" first, while the actual number is not changed in translation (we are still looking at the same flock of sheep). And the "vier" and "zwanzig" are written in straight L-to-R order (no bidi in German then, ''all'' is L-to-R).  -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 10:05, 15 March 2012 (UTC)
::::: ''[O]f course within a decimal number the order is important. It says which is the tenners (2) and the one'rs (4)'':
::::: With all due respect, I think you're missing my point, DePiep. Within a decimal number, '''left-right orientation''' is important, saying which place is the tens, which is the ones, etc. I'm saying that left-right orientation is not the same thing as "order". In "24", the ''rightmost digit'' stands for the ones' place, the ''next-to-rightmost digit'' stands for the tens' place. Which of those digits is written first? Well, that depends on whether you're writing from right to left or from left to right, doesn't it?

::::: Here's what I think the key question is: would an Arabic writer setting down the number "24" (or "٢٤‬") naturally switch the direction of his writing to write the number from left to right, setting down the 2 first, or would he continue going from right to left, setting down the 4 first? Not being an Arabic speaker, I don't know the answer to that, but I don't see a reason to assume that he would change directions when he got to numerals.

::::: You and BIL have mentioned text editors and Unicode, which may be a different story. If most (or all?) text editors using Unicode treat (Eastern) Arabic numerals as having a left-to-right orientation, I can see how that might be worth adding to the article, but in that case, I think it should be made clear that we're talking about text that's treated as bidirectional ''in a standard text editor'', as opposed to something that's inherent in Arabic script. [[User:JudahH|JudahH]] ([[User talk:JudahH|talk]]) 16:21, 16 March 2012 (UTC)
::::::OK, so it is about ''entering sequence'' (typing sequence). I don't do R-to-L scripts (Hebrew, Arab), but if I'm correct this is how it works in a modern browser: of one enters Arabic text, andthen starts typing a (decimal) number, one types &rarr;{{key press|2}}{{key press|4}} and the browser puts them in the right order. So in the process, one sees the "4" being put in place between the earlier text and the (already present) "2". Then entering a space and more regular Arabic text, this is added to the left of the "24". I do not think that one has to reorder the sequence yourself, nor change any direction. The browser does that for you. The same can be said about entering telephone numbers, right? One spells, reads, phone-typing-enters, and writes telephone numbers always in one same sequence. Even in handwriting. Since they are decimal numbers (could be EA?), the browser knows how to handle that. -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 17:07, 16 March 2012 (UTC)
::::::Your last point here: I am not that sure about reentering the text in the page (don't know if it is in the right context and the 2nd part is dubious), but I do think it is correct. -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 17:07, 16 March 2012 (UTC)
::::This is mainly a technical article, not so much a lingustic one. If the Eastern Arabic numerals are entered through keyboard and stored left-to-right, then they are considered left-to-right from technical point of view. In my editor, an arabic text with an Eastern Arabic number in it is stepped through right-to-left, except that the number is stepped through left-to-right. --[[User:BIL|BIL]] ([[User talk:BIL|talk]]) 11:06, 15 March 2012 (UTC)

:::::Agree, bidi text is a technical topic. Although the page title does not say so, bidi writing is mainly an Unicode issue, which browsers use as a standard. Unicode describes & defines it in UAX#9 "Unicode Bidirectional Algorithm". One of the first things to know: the ''logical sequence'' of characters, aka memory representation, is allways L-to-R and does not change (most likely that is also the sequence of entering characters, and the sequence that is saved in a file). The browser does this: it adds a ''presentation sequence'' of characters parallel to that memory sequence. In that sequence, all the bidi-rules are applied  (e.g. an Arab text string is inversed, R-to-L). Then this presentation sequence is fed to the screen for showing. Still, the memory sequence is unchanged.
:::::I thought I was supporting part of your edit (although I cannot understand or support the part that says "Arabic text may be L-to-R too").
:::::If you mean to say "keyboard entering sequence can be L-to-R", this is confusing (and wrong): the entering sequence is a ''time'' sequence (and is put directly in the ''memory sequence'' I mentioned). Just think of what you would type with your eyes closed, or when spelling it through a telephone: would you have to ''care'' about direction? No. As for your what you see in your edit screen: that is the browser (or text editor) at work: it already has done its job getting the ''presentation sequence'' right, and shows it. -[[User:DePiep|DePiep]] ([[User talk:DePiep|talk]]) 11:30, 15 March 2012 (UTC)
:Correct. This is called [[endianness]], and is an important part of computer science. While Arabic numerals always have the big side on the left, the endianness depends on the direction of reading.[[User:Scientus|Scientus]] ([[User talk:Scientus|talk]]) 18:23, 25 May 2015 (UTC)
