U+31F6 Katakana Letter Small Hi

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

ひ, in hiragana, or ヒ in katakana, is one of the Japanese kana, which each represent one mora. Both can be written in two strokes, sometimes one for hiragana, and both are phonemically /hi/ although for phonological reasons, the actual pronunciation is [çi] , the sound would be nearer to be transcribed "hyi" in phonetic-based rōmaji. The pronunciation of the voiceless palatal fricative [ç] is similar to that of the English word hue [çuː] for some speakers.

In the Sakhalin dialect of the Ainu language, ヒ can be written as small ㇶ to represent a final h sound after an i sound (イㇶ ih). Along with other extended katakana, this was developed to represent sounds in Ainu that are not present in standard Japanese katakana.
