 Thanks, to be honest, I presently have no idea in which code this
 `CFStringGetLongCharacterForSurrogatePair` is being called. Somewhere in
 `gdk-pixbuf2`? Also, I tried to find some c code for an "on foot" solution
 of the 32bit UTF encoding of a surrogate pair of two 16bit parts, but did
 not easily found one.
