U+FE55 Small Colon

U+FE55 was added in Unicode version 1.1 in 1993. It belongs to the block U+FE50 to U+FE6F Small Form Variants 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 a small version of the glyph Colon. Its East Asian Width is wide. 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+FE55 prohibits line breaks before its position. There might be some exceptions, though.

The Wikipedia has the following information about this codepoint:

The colon, :, is a punctuation mark consisting of two equally sized dots aligned vertically. A colon often precedes an explanation, a list, or a quoted sentence. It is also used between hours and minutes in time, between certain elements in medical journal citations, between chapter and verse in Bible citations, and, in the US, for salutations in business letters and other formal letter writing.
