o another linux console patch by Nikolay Nikolov:

Browse Source 
* disabled linux VCSA output in UTF-8 mode, because it does not do any translation 
  and assumes that the font is cp437, or similar, which looks horrible on fonts 
  (like fedora's default latarcyrheb-sun16), which are designed only for unicode 
  support and have no similarity at all to cp437. We already can display all the 
  cp437 characters in UTF-8 mode (including the low 32 characters), in case the 
  font is cp437, and the UTF-8 translation provides better approximation (e.g. 
  for the line drawing characters) if the font is not cp437.
* do not "restore" the linux system font in SysDoneVideo in UTF-8 mode, 
  since we didn't change the font on startup
* added try_grab_vcsa to try harder to open VCSA in the linux IDE user 
  screen restore code. While VCSA is no longer needed in the video unit on 
  UTF-8 systems, the IDE still needs it, because it's the only way to provide 
  the "restore user screen" functionality on the linux virtual console.
