Is anyone using the polytonic Greek spell file successfully? I get
Error detected while processing /Users/lawrence/.vim/spell/polytonic.utf-8.spl:
E763: Word characters differ between spell files.
PS. Sorry, I was impræcise before: I get this error only when combining Greek with English, after
set spell and
set spelllang=polytonic,en_gb (regardless of whether in .vimrc or session). It works fine, though; but the error message is a bit annoying.
