Function: decode-char

decode-char is a function defined in charset.c.

Signature

(decode-char CHARSET CODE-POINT)

Documentation

Decode the pair of CHARSET and CODE-POINT into a character.

Return nil if CODE-POINT is not valid in CHARSET.

CODE-POINT may be a cons (HIGHER-16-BIT-VALUE . LOWER-16-BIT-VALUE), although this usage is obsolescent.
