Letterlike Symbols are symbols derived in some way from
ordinary letters of an
alphabetic script. Most are encoded for
compatibility with existing character sets.
Despite its name, U+2118 ℘ script capital P ℘ is neither script nor capital -- it is uniquely the Weierstrass elliptic function derived from a calligraphic lowercase p.
The black letter style is often referred to as Fraktur or Gothic, which are distinct designs from black, but are not distinguished in any existing encoding.
Unicode's
Letterlike Symbols code block reserves the
80 code points from U+2100 to U+214F, of which all 80 are currently assigned.
