Macron below

A̱a̱ḆḇC̱c̱

Macron below is a combining diacritical mark that is used in various orthographies.

A non-combining form is Template:Unichar. It is not to be confused with Template:Unichar, Template:Unichar and Template:Unichar. The difference between "macron below" and "low line" is that the latter results in an unbroken underline when it is run together: compare a̱ḇc̱ and a̲b̲c̲ (only the latter should look like abc).

Precomposed characters

Various precomposed letters with a macron below are defined in Unicode:

upper case			lower case			notes
letter	Unicode	HTML	letter	Unicode	HTML
Ḇ	U+1E06	Ḇ	ḇ	U+1E07	ḇ	Used in the transliteration of Biblical Hebrew into the Roman alphabet to show the fricative value of the letter beth () representing [v], or perhaps Template:IPAblink.
Ḏ	U+1E0E	Ḏ	ḏ	U+1E0F	ḏ	Used in the transliteration of Biblical Hebrew, Syriac and Arabic into the Roman alphabet to show the fricative value of the letter dalet (ד), Template:IPAblink, and in the romanization of Pashto, it is used sometimes to represent retroflex D. In Dravidian languages' transcription it represents an alveolar /d/.
			ẖ	U+1E96	ẖ	Sometimes used for Arabic ẖāʼ, Hebrew Heth (letter), Egyptian . There is no precomposed upper case equivalent of ẖ so it uses a combining macron below instead: H̱.
Ḵ	U+1E34	Ḵ	ḵ	U+1E35	ḵ	Used in the transliteration of Biblical Hebrew into the Roman alphabet to show the fricative value of the letter kaph () representing Template:IPAblink. Used in Tlingit and Haida (among other Pacific Northwest languages) for the voiceless uvular stop Template:IPAblink. Close to Korean ㄲ kk; closest English "shocking" Used optionally in the K-dialect of Māori in the South Island of New Zealand, where an original ng has merged with k. The ḵ indicates that it corresponds to ng in other dialects. There is no difference in pronunciation between ḵ and k.
Ḻ	U+1E3A	Ḻ	ḻ	U+1E3B	ḻ	One possible transliteration of the Dravidian retroflex approximant /ɻ/ as in Tamil letter ழ. Ḻ is used in the Seri language to represent Template:IPAblink, like English l, while unmodified "l" represents Template:IPAblink, like Welsh ll. It is also used in the proposed Unified Alphabet for Mapudungun.
Ṉ	U+1E48	Ṉ	ṉ	U+1E49	ṉ	Used in Pitjantjatjara to represent Template:IPAblink, and in Saanich to represent both plain and glottalized Template:IPAblink. In the romanization of Pashto, it is used sometimes to represent retroflex N. In Dravidian languages' transcription it represents an alveolar /n/.
Ṟ	U+1E5E	Ṟ	ṟ	U+1E5F	ṟ	Used in Pitjantjatjara to represent Template:IPAblink, and sometimes in the romanization of Pashto to represent the retroflex R. In Dravidian languages' transcription it represents an alveolar trill /r/.
Ṯ	U+1E6E	Ṯ	ṯ	U+1E6F	ṯ	Used in the proposed Unified Alphabet for Mapudungun language representing Template:IPAblink. In the romanization of Pashto, it is used sometimes to represent retroflex T. In Dravidian languages' transcription it represents an alveolar /t/. In the romanization of Arabic this letter is used to transcribe the letter Ṯāʾ.
Ẕ	U+1E94	Ẕ	ẕ	U+1E95	ẕ	Used in the 1953 Hebrew Academy Romanization of Hebrew to represent tsade ().
₫	U+20AB	₫				Vietnamese đồng.

Note that the Unicode character names of precomposed characters whose decompositions contain Template:Unichar use "WITH LINE BELOW" rather than "WITH MACRON BELOW". Thus, Template:Unichar decomposes to Template:Unichar and Template:Unichar.

The Vietnamese đồng currency sign resembles a lower case d with a stroke and macron below: Template:Unichar but is neither a letter nor decomposable.
