U+0124 "Ĥ" Latin Capital Letter H with Circumflex Unicode Character
Unicode Version 17.0
Ĥ
U+0124 "Ĥ" Latin Capital Letter H with Circumflex is a distinct grapheme used primarily in written Esperanto, where it represents a voiceless velar fricative sound, akin to the "ch" in the Scottish word "loch". The circumflex diacritic above the H signals this specific pronunciation, which is a unique aspect of Esperanto's orthography designed by its creator L. L. Zamenhof. In Unicode, this character belongs to the Latin Extended-A block and is encoded for digital text representation alongside its lowercase counterpart "ĥ" (U+0125). While it is most frequently encountered in Esperanto texts and linguistic discussions, it may also appear in phonetic transcription or other specialized contexts where a similar sound is needed.
