Unicode Version 17.0
ᵪ
U+1D6A "ᵪ" Greek Subscript Small Letter Chi is a typographic variant of the Greek letter chi (χ) designed to appear lowered beneath the baseline, functioning primarily as a phonetic or diacritic subscript symbol in certain transcription systems. It is encoded in the Unicode Phonetic Extensions block and is used in linguistic contexts, such as representing a voiceless uvular fricative in some orthographies or aiding precise phonetic notation in scholarly works. This character allows for compact textual representation without altering the main line of text, and it should not be confused with the standard Greek chi or other subscript modifiers.
