U+20DB "⃛" Combining Three Dots Above Unicode Character

U+20DB "⃛" Combining Three Dots Above is a diacritical mark used in written language to modify or combine with a preceding base character, typically to indicate a specific phonetic or grammatical feature. It consists of three small dots arranged in a horizontal line placed above the character it follows, and its Unicode categorization as a combining mark means it does not stand alone but rather attaches to and alters the appearance or meaning of the base glyph. Historically, it has been employed in certain transliteration systems or phonetic notations, such as representing a particular tone or speech sound, and it is rendered in text by typing the base character first and then appending this combining sequence, with proper support depending on the font and application used.
