Hmm... 

There might be a relatively simple way around that, if GD assumes TTF fonts: the UCS-2 cmap subtable is an impossible candidate for characters with code 0x10000 and up, as these are wider than 2 bytes (which is what the '2' in UCS-2 stands for). Effectively, if a character is more than 2 bytes, GD could skip straight to the UCS-4 cmap subtable instead, and resolve the character there.

I use this shortcutting in my own OTF/TTF parser, too.

(Of course, this does not work for OTF fonts with CFF content, but then I seem to recall GD doesn't actually support those)
