U+005C Reverse Solidus

U+005C 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 character is also known as backslash.

The glyph is not a composition. Its East Asian Width is narrow. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. U+005C prohibits a line break after it, if it is followed by a number. The glyph can be confused with 14 other glyphs.

The CLDR project calls this character “backslash” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: reverse solidus, whack.

The Wikipedia has the following information about this codepoint:

The backslash is a mark used mainly in computing and mathematics. It is the mirror image of the common slash /. It is a relatively recent mark, first documented in the 1930s. It is sometimes called a hack, whack, escape (from C/UNIX), reverse slash, slosh, downwhack, backslant, backwhack, bash, reverse slant, reverse solidus, and reversed virgule.
