right-to-left languages are really, really, really well supported in
vim.  at least, they seem to be.  check out:

   :set rl

all the vim commands i can think of work well.


the language i'm thinking of is hebrew, but with some important issues.

1. i need vowel support.
2. i really want to have mixed hebrew/english

i believe taken together, i want to use ISO 10646 which can represent
all languages at the same time.

as a first stab at getting utf-8 capable xterms, i set:

   LC_CTYPE=en_US.UTF-8

but wierd things started to happen, like mutt's threading lines turned
into really strange characters.  i guess the applications themselves
need to be utf-8 aware too.

that makes me very sad...   :(

okay.  it never is that easy, eh?   :-)

it totally sucks that mixed hebrew-with-vowels/engish turned out to be
such a hard thing to do.  :( sucks even worse that it's easy on windows
xp.   :(
