Ĥ

Ĥ or ĥ is a letter of some extended Latin alphabets, most prominently a consonant in Esperanto orthography, where it represents a voiceless velar fricative [x] or voiceless uvular fricative [χ]. Its name in Esperanto is ĥo (pronounced /xo/), or ĥi in the Kalocsay abecedary.

It is also used in the revised Demers/Blanchet/St Onge orthography for Chinook Jargon.

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 is the eleventh letter in Esperanto orthography. Although it is written as hx and hh respectively in the x-system and h-system workarounds, it is normally written as H with a circumflex: ĥ.
