Thanks Don for your reply.
I may have overlooked something in the blog post you gave, but my
understanding is that it talks about the user's input/output to and
from GHCi and the file system. The user IO with non-Latin chars seems
to work fine in GHC 6.12.1; e.g.:
*Main> putStrLn "πρόχειρον.hs"
πρόχειρον.hs
*Main> getLine >>= putStrLn
πρόχειρον.hs
πρόχειρον.hs
*Main>
It's only when GHCi attempts to print a diagnostic message containing
a filename with non-Latin chars that the garbling occurs:
*Main> :load πρόχειρον.hs
[1 of 1] Compiling Main ( ÏÏÎ
¿ÌÏειÏον.hs, interpreted )
ÏÏοÌÏειÏον.hs:1:23:
Not in scope: type constructor or class `Boo'
Failed, modules loaded: none.
Prelude>
It would be nice if the error messages at least showed correctly the
filename.
Maybe this has something to do with Haskeline?
Anyway thanks again,
Christos

Ok, modules loaded: Main.

Is this expected, or something is wrong with my setup? It's a rather
insignificant issue, but I thought to ask about it.
I'm using GHC 6.12.1rc1 on Mac OS X 10.6.1.
Perhaps you're seeing the GHC support for locales in 6.12.
