netsurf/riscos/save.c
John Mark Bell f4ecaaed31 [project @ 2005-07-16 14:35:20 by jmb] 
- Convert Messages files to UTF-8 encoding.
- Replace local_encoding_name() with platform specific
  utf8_[to,from]_local_encoding() functions - this allows mapping of 8bit
  characters 0x80->0x9f (inclusive).
- All text that is rendered by the RISC OS Wimp is now converted to the system
  local encoding prior to display.
- Lose the horrendous hack that was messages_get_key()
- Menu text is now translated to system local encoding on the fly (if necessary)
  rather than at menu creation time. This allows the system alphabet to change
  under us and our menus remain usable.
- The Languages menu now lists all languages that are present in the LangNames
  file. In the case of selecting the UI language, those languages which are not
  available are shaded.
