NAME
       FcCharSetMerge - Merge charsets

SYNOPSIS
       #include <fontconfig/fontconfig.h>

       FcBool FcCharSetMerge (FcCharSet *a, const FcCharSet *b, FcBool *changed);

DESCRIPTION
       Adds  all chars in b to a.  In other words, this is an in-place version of FcCharSetUnion.  If changed is not NULL, then it returns whether
       any new chars from b were added to a.  Returns FcFalse on failure, either when a is a constant set or from running out of memory.

VERSION
       Fontconfig version 2.10.95
