This character is a Math Symbol and is commonly used, that is, in no specific script. The character is also known as solidus (in typography).
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it is written as number separator according to the number it separates. When changing direction it is not mirrored. U+2044 prohibits a line break after it, and before it, too, if preceded by a number. The glyph can be confused with one other glyph.
The CLDR project calls this character “fraction slash” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: stroke, virgule.
This character is distinct from U+2215 DIVISION SLASH. It is
intended to represent an actual fraction, not the operation of dividing. In
some fonts combining it with numbers leads to a ligature display like “½”. For

The Wikipedia has the following information about this codepoint:
The slash is the oblique slanting line punctuation mark /. It is also known as a stroke, a solidus, a forward slash and several other historical or technical names. Once used to mark periods and commas, the slash is now used to represent division and fractions, exclusive 'or' and inclusive 'or', and as a date separator.
A slash in the reverse direction is known as a backslash.
