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.
