[Haskell-cafe] ghci can't load file whose name contains non-ASCII chars?

I must be making some obvious mistake here,
but I'm not seeing it. The file name contains O-umlaut,
and the OS handles it fine, but ghci does not like it
(although it accepts umlauts in the contents of the file
(UTF-8) e.g., as a module name)

$ cat fÖÖbar.hs 
main = print $ product [1..100]

$ ghci fÖÖbar.hs 
GHCi, version 7.4.1: http://www.haskell.org/ghc/  :? for help

<no location info>: can't find file: f??bar.hs

this is on a standard ubuntu install (11.10 and 11.04) with 

$ locale
