U+2137 GIMEL SYMBOL: ℷ – Unicode

U+2137 was added in Unicode version 1.1 in 1993. It belongs to the block U+2100 to U+214F Letterlike Symbols in the U+0000 to U+FFFF Basic Multilingual Plane.

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 Hebrew 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:

In axiomatic set theory, the gimel function is the following function mapping cardinal numbers to cardinal numbers:

$ℷ : κ \mapsto κ^{c f (κ)}$

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