21     2002/Apr. Keita KAWABE
22     * Support for narrow build Asian Psions added.
23    
24     Now psiconv understands -u or --UTF8 option.
25     This option is passed to output_function as the fourth parameter
26     (thus the typedef of output_function was changed).
27    
28     If a called generator (gen_*.c) can handle UTF8, then it handles
29     the character conversion etc. accordingly.
30    
31     * psiconv seemed to want to take the argument of the options
32     case-insensitively (i.e. LaTeX -> LATEX), but that was not working
33     under my environment. Fixed it.
