U+10797 "𐞗" Modifier Letter Small Heng with Hook Unicode Character

U+10797 "𐞗" Modifier Letter Small Heng with Hook is a diacritic mark used in the International Phonetic Alphabet to represent a specific phonetic modification, typically indicating a more retracted or rhotacized articulation of a base sound. This character is part of the Latin Extended F block and is derived from the shape of the letter "heng," which itself resembles a lowercase "h" with a hook, but in a small, superscript form. Its primary function is as a modifier to alter the pronunciation of a preceding or adjacent letter, often in the transcription of nuanced or obscure speech sounds in languages such as those of West Africa or in descriptive linguistics. Because it is a relatively recent addition to the Unicode standard, it is not widely supported in all fonts or text systems.
