wxMac 2.8.7: problem reading date of files with unusual chars in file name

[Fulvio Senore]

I have very little experience with OSX, so I do not know anything about 
encoding and similar things.

Anyway, it looks like GetModificationTime() does not work correctly with 
filenames containing accented letters in OSX. If confirmed, this looks 
like a bug to me and I think that it would be nice if it were fixed.
I suppose that I could find a workaround using native calls, but this is 
against the spirit of wxWidgets.
