+1 for integrating Unicode file paths. Thanks, Bulat!

I think the most important use cases that should not break are:

o open/read/write a FilePath from getArgs
o open/read/write a FilePath from getDirectoryContents

There's not much we can do about non-Latin-1 ACP file paths
hard coded in Strings. I hope there aren't too many
of those in the wild.
