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. open_dir_handle), 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.
