U+10790 "𐞐" Modifier Letter Small Feng Digraph Unicode Character

U+10790 "𐞐" Modifier Letter Small Feng Digraph is a specialized symbol belonging to the Latin Extended G block, designed to represent a phonetic digraph in certain linguistic transcription systems, particularly for documenting pronunciations in the Jurchen language and other historical or minority languages of East Asia. It visually resembles a small, superscript version of the letter "F" fused with the "Eng" digraph, and its primary function is to modify the preceding letter to indicate a specific co-articulated or affricate sound, such as a labiodental or velar nasal release. This character was added to Unicode in version 14.0 in 2021 to support scholarly work in historical linguistics and philology, enabling precise notation of sound distinctions that standard Latin letters cannot capture effectively.
