U+003A Colon

U+003A was added in Unicode version 1.1 in 1993. It belongs to the block U+0000 to U+007F Basic Latin in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Punctuation and is commonly used, that is, in no specific script.

The glyph is not a composition. Its East Asian Width is narrow. In bidirectional text it is written as number separator according to the number it separates. When changing direction it is not mirrored. It will not end a sentence. U+003A prohibits a line break after it, and before it, too, if preceded by a number. The glyph can be confused with 19 other glyphs.

The CLDR project calls this character “colon” for use in screen reading software.
