Fair enough.

Well, IMO, the best place to patch this would be in chartrans.c, where
bReadCharacterMappingTable() tries to open the file (if it's NULL, try
adding ".txt" and opening that)...

Try the attached patch.  FWIW, it seems like there's a bug here, but
sscanf used to mask it.  Was there a change in the sscanf implementation
since 1.5.9?
