Many thanks for your reply and all the subsequent followups and bugfixing.

The workaround you propose seems a little complex and it might be a bit
problematic that 100% roundtripping can't be guaranteed even once your
fix is applied. Do you think it would be reasonable/feasible for darcs
to have its own version of getDirectoryContents that doesn't try to do
any translation in the first place? It might make sense to make a
separate package that others could use to.

BTW I was trying to find the patch where this changed but couldn't - was
it a consequence of
https://github.com/ghc/packages-base/commit/509f28cc93b980d30aca37008cbe66c677a0d6f6
?

Cheers,
