I do not think this expectation is reasonable. I do not think that ls
is Unicode-aware. It probably has only bytes semantic, not characters

"locale aware application" is too vague. An application can use the
locale and still being unable to separate bytes from characters. ls
may be "locale aware" but it is probably not "Unicode aware".

This is not an Haskell issue but a ls issue. use
System.Directory.getDirectoryContents and we'll see.
