Right, conv_uni_to_pc() properly checks:
  if (ucs > 0xffff)
      return -4;
before
  dir = dict->uni_pgdir[UNI_DIR(ucs)];


Even better!

I also noted to my TODO to check why ucs is "long" there. It makes no 
sense at all. Be it negative, or long-sized. IMO, it should simply be u32.

There is so much crap in the code :/...
