Wow, that's surprisingly lame.

It isn't really correct.  I'm not overly concerned about the corner
cases though (the difference is that in theory with ASCII you should
get an error if you see a byte >0x7f, but with UTF-8 we'll try to
interpret it).

I think something like this would be fine, especially if it comes with
a big comment explaining why it is required (like the one in libgcj).
Do you want to try it?  I think it might suffice to fix
gcc/java/lex.c.

Longer term, consider installing Bruno Haible's libiconv.
