(Frodo) Psiconv program rewrite start
  * Add support for different encodings
  * Restructure some things
  * Only ASCII support at the moment

20 /*
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.
