This character is a Other Letter and is commonly used, that is, in no specific script. The character is also known as third transfinite cardinal (functions of a real variable).
The glyph is a compatibility version of the glyph Glyph for U+05D2Hebrew Letter Gimel. It has no designated width in East Asian texts. In bidirectional text it is written from left to right. When changing direction it is not mirrored. The word that U+2137 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.
The Wikipedia has the following information about this codepoint:

where cf denotes the cofinality function; the gimel function is used for studying the continuum function and the cardinal exponentiation function. The symbol is a serif form of the Hebrew letter gimel.
