It is also used in the revised Demers/Blanchet/St Onge orthography for Chinook Jargon.[1]
In the case of the minuscule, some fonts place the circumflex centered above the entire base letter h, others over the riser of the letter, and others over the shoulder.

"Ĥ" was created by adding a circumflex to an ordinary "H". It first appeared as part of the alphabet of the international languageEsperanto, with the publication of the Unua Libro on 26 July 1887 marking the beginning of its wider usage.[2] Like all other non-basic Latin letters in the Esperanto alphabet, it was inspired by Western Slavic Latin alphabets (e.g. Czech), but uses a circumflex instead of a caron — most likely to make the orthography appear more international (i.e. less Slavic) and more compatible with French typewriters, which were in general use at the time and had a dead key for the circumflex, allowing it to be typed over any character.
Reported end
⟨Ĥ⟩ was always the least frequent letter in Esperanto orthography,Template:Efn occurring mostly in words with Greek etymologies, where it represented a Romanized chi (in fact its name in the Kalocsay abecedary, Script error: No such module "Lang"., was most likely inspired by this usage). Since chi is pronounced Script error: No such module "IPA". in most languages, neologistic equivalents soon appearedTemplate:Why in which ⟨ĥ⟩ was replaced by ⟨k⟩, such as Script error: No such module "Lang".Template:Nbsp→ Script error: No such module "Lang". ("technology") and Script error: No such module "Lang".Template:Nbsp→ Script error: No such module "Lang". ("chemistry"). Such changes were probably due to the 'k' sound being easier to pronounce by most European speakers, and the resulting word sounding more similar to the native equivalent. Some other replacements followed different patterns, such as Script error: No such module "Lang".Template:Nbsp→ Script error: No such module "Lang". ("Chinese [person]").
These additions and replacements came very early and were in general use by World War I. Since then, the end of ⟨ĥ⟩ has been often discussed, but has never really happened. In modern times (post-World War II), no new coinages intended to replace words with ⟨ĥ⟩ in them have seen general use, with the notable of exception of Script error: No such module "Lang". for Script error: No such module "Lang". ("chorus"). Some words originally containing a ⟨ĥ⟩ are preferred to existing replacements (old or new), such as Script error: No such module "Lang". vs. Script error: No such module "Lang". ("chaos").Script error: No such module "Unsubst".
Several words commonly use ⟨ĥ⟩, particularly those not derived from Greek words (Script error: No such module "Lang". ("khan"), Script error: No such module "Lang". ("jota"), Script error: No such module "Lang". ("Liechtenstein"), etc.) or those in which there is another word that uses "k" in that context. The latter include:
Script error: No such module "Lang". ("echo") ≠ Script error: No such module "Lang". ("beginning")
Script error: No such module "Lang". ("Czech") ≠ Script error: No such module "Lang". ("bank check")
Script error: No such module "Lang". ("chorus") ≠ Script error: No such module "Lang". ("heart") ≠ Script error: No such module "Lang". ("hour")
Other uses
A 'Ĥ' was used in the stage name of the 1980s Italo disco singer CĤATO.[3]
