The client - only the client definately supports its local codepage (a 
Linux server for example normally has no idea about Windows codepages).

AFAIK there's no tool, unless someone has written on.  As it also 
affects cvshome there's a chance there is one out there somewhere.

In theory - just never had the time to spend on it... it needs a basic 
RCS parser and something to do the conversion.

Unix supports UTF8 natively so if the client is running in it then 
everything just works as normal - the user really doesn't need to care 
about it.  If cvsnt spawns vi for example it (should) inherit the 
codepage of the client so the editing is done in the right codepage.

(the oddity is OSX, where the locale functions don't affect the file I/O 
  (which is always in UTF8) so you have to run in UTF8 always otherwise 
stuff doesn't work).
