U+02E3 "ˣ" Modifier Letter Small X Unicode Character

U+02E3 "ˣ" Modifier Letter Small X is a spacing glyph that functions as a superscript or raised version of the lowercase Latin letter X, used primarily in phonetic transcription to indicate secondary articulation, aspiration, or as a diacritic modifier in linguistic notations such as the International Phonetic Alphabet. It appears as a small x positioned slightly above the baseline, and its primary role is to modify the sound of a preceding or following character, often representing palatalization or a velar fricative component in certain language orthographies and scholarly works on phonetics.
