Dir.glob does not support unicode on Windows
|ruby -v:||ruby 1.9.2dev (2009-09-02) [i386-mswin32_90]||Backport:|
Although there are some methods which support wide characters (e.g. opendirhandle), at the end, the directory listing does not work or returns array with corrupted entry names. This applies to both, trunk and also win32-unicode-test branch.
