U+2212 Minus Sign

U+2212 was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 to U+22FF Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math 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 as European number separator from left to right. When changing direction it is not mirrored. U+2212 prohibits a line break after it, if it is followed by a number. The glyph can be confused with one other glyph.

The CLDR project calls this character “minus” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: odejmować, odejmowanie.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

Plus ( + ) i minus ( − ) – oznaczenia matematyczne stosowane do wyróżniania operacji dodawania i odejmowania.
