U+A789 Modifier Letter Colon

U+A789 was added in Unicode version 5.1 in 2008. It belongs to the block U+A720 to U+A7FF Latin Extended-D in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Modifier Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+A789 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

The Wikipedia has the following information about this codepoint:

The colon alphabetic letter ꞉ is used in a number of languages and phonetic transcription systems, for vowel length in Americanist Phonetic Notation, for the vowels ⟨a꞉⟩ [ɛ] and ⟨o꞉⟩ [ɔ] in a number of languages of Delhi, India, and for grammatical tone in several languages of Africa. It resembles but differs from the colon punctuation mark, :. In some fonts, the two dots are placed a bit closer together than those of the punctuation colon so that the two characters are visually distinct. In Unicode it has been assigned the code U+A789 ꞉ MODIFIER LETTER COLON, which behaves like a letter rather than a punctuation mark in electronic texts. In practice, however, an ASCII colon is frequently used for the letter.

In Windows and macOS, the letter colon can be used to emulate the punctuation colon in file names, where the punctuation colon is a reserved character that cannot be used.
