NAME
FcCharSetMerge - Merge charsets
SYNOPSIS
#include <fontconfig.h> FcBool FcCharSetMerge(FcCharSet *a); (const FcCharSet *b); (FcBool *changed); .fi
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.
