You probably forgot to bump the declaration "int charset[0x100];" to 
something larger. But you can't use Unicode characters like that anyway. 
Have a look at dumb16.conf and/or dumb32.conf for a way to do it: Those 
two modes work with UTF-16 and UTF-32 internally and has a final 
conversion from that into UTF-8.
