U+2155 Vulgar Fraction One Fifth

U+2155 was added in Unicode version 1.1 in 1993. It belongs to the block U+2150 to U+218F Number Forms in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Number and is commonly used, that is, in no specific script. The codepoint has the numeric value 1/5.

The glyph is a fraction composition of the glyphs Digit One, Fraction Slash, Digit Five. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+2155 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
