    2002/Apr.    Keita KAWABE
    * Support for narrow build Asian Psions added.

    Now psiconv understands -u or --UTF8 option.
    This option is passed to output_function as the fourth parameter
    (thus the typedef of output_function was changed).

    If a called generator (gen_*.c) can handle UTF8, then it handles
    the character conversion etc. accordingly.

    * psiconv seemed to want to take the argument of the options
    case-insensitively (i.e. LaTeX -> LATEX), but that was not working
    under my environment. Fixed it.
