This character is a Dash Punctuation and is commonly used, that is, in no specific script. The character is also known as hyphen or minus sign.

The glyph is not a composition. It has a Narrow East Asian Width. In bidirectional context it acts as European Separator and is not mirrored. The glyph can, under circumstances, be confused with 10 other glyphs. In text U+002D behaves as Hyphen regarding line breaks. It has type SContinue for sentence and Other for word breaks.

The Wikipedia has the following information about this codepoint:

The hyphen-minus ( - ) is a character used in digital documents and computing to represent a hyphen ( ) or a minus sign ( ) . It is present in Unicode as code point U+002D - hyphen-minus; it is also in ASCII with the same value.

The use of one character for hyphen and minus, and sometimes also for en dash, was a compromise made in the early days of fixed-width typewriters and computer displays. However, in proper typesetting and graphic design, there are distinct characters for hyphens, dashes, and the minus sign. Usage of the hyphen-minus nonetheless persists in many contexts, as it is well-known, easy to enter on keyboards, and in the same location in all common character sets.

Most programming languages, restricting themselves to ASCII, use the hyphen-minus, rather than the Unicode character U+2212 − minus sign, for denoting subtraction and negative numbers.

Commonly, an em dash is represented by two hyphen-minus signs in succession, or even three in TeX markup.
