pandoc dislikes non-ASCII filenames under ghc-7.4.1

[trofi]

Starting from ghc-7.2 'System.Environment.getArgs' started returning expected values

Unfortunately it broke pandoc

# undef ghc-7.4
$ ~/dev/git/pandoc:touch Привет.rst
$ ~/dev/git/pandoc:dist/build/pandoc/pandoc Привет.rst Привет.html
$ pandoc: ÐÑивеÑ.rst: openFile: does not exist (No such file or directory)

It was easy to fix for simple project:
styx/gtc@ba5f07d

Partially it's an utf8-strng fault

PS. I'm not sure this is the right base version to test for. Do you know which version of base started properly encoding file paths and arguments? (Or were file paths and command line arguments fixed in different versions of base?) It would be good to get this right, even though this version works with ghc 7.4.*.

Thank you!

Both were added in ghc-7.2. The commit:

https://github.com/ghc/packages-base/commit/509f28cc93b980d30aca37008cbe66c677a0d6f6

and it's tree:

https://github.com/ghc/packages-base/blob/509f28cc93b980d30aca37008cbe66c677a0d6f6/base.cabal

Thus base-4.4.0.0 had the change.

Thanks. I'll test for 4.4 then instead of 4.5.
