5754,Cabal cannot register a package in a directory with Unicode chars,simonmar,simonmar,"While fixing #5697, I tried building and registering a package in a directory with Unicode chars, and cabal-install fails to register it.

This appears to be a regression since 7.0, as it first fails with 7.2 and is still failing in 7.4.

I'm not sure who's fault this is, but since it is GHC-version dependent it could well be ours.

I tried with cabal-install 0.8 and 0.10:

I haven't tried building cabal-install with 7.2 yet.
