U+20F0 "⃰" Combining Asterisk Above Unicode Character

U+20F0 "⃰" Combining Asterisk Above is a combining diacritical mark that is designed to be placed over a preceding base character, such as a letter, in order to modify its meaning or pronunciation. Distinct from a standard asterisk symbol, this character is used primarily in linguistic and academic contexts, including in some notations for Indo-European and Proto-Semitic reconstructions, where it can denote a reconstructed phoneme or a specific phonetic feature. When rendered properly in supported fonts, it appears as a small, star-shaped glyph positioned above the baseline, and it relies on its preceding character for correct visual alignment within text.
