Can you have both KOI-R and ISO8859-15?

Hi --

 I guess I am falling in a strange intersection...I need to be able to
read/work with Russian and Latin-1 on my system. Russian filenames are
just gibberish right now...
 Is there a way to have both? Or is this a problem that'll only get
solved with Unicode? More and more we need to use foreign languages
these days for our work...

 TIA,
