U+A789 "꞉" Modifier Letter Colon Unicode Character
Unicode Version 17.0
꞉
U+A789 "꞉" Modifier Letter Colon is a punctuation mark designed specifically for phonetic transcription, where it represents a lengthened or prolonged sound of a preceding vowel or consonant, functioning like a triangular colon or IPA length mark. It is distinct from the regular ASCII colon (U+003A) as it is intended to be used within alphabetic strings rather than in general text or time notation, allowing it to appear as a modifier attached to letters without breaking word boundaries in digital text processing.
