>>From libcpp/lex.c:
      /* Grab user defined literal suffix.  */
      else if (ISIDST (*pos))
        {
          type =3D cpp_userdef_string_add_type (type);
          ++pos;

          while (ISIDNUM (*pos))

Hmm, that looks wrong for non-ASCII codes.

I suspect the preprocessor/lexer has other issues with non-ASCII code in ot=
her
areas too.=
