Bug #5570: Encoding of environment variables on Windows
http://redmine.ruby-lang.org/issues/5570

It seems that the filesystem encoding is forced upon environment variables.  There is, however, no guarantee that this encoding is the correct one.  Getenv() probably shouldn???t be used on Windows at all.  Using _wgetenv instead should guarantee that the returned result is encoded properly and it can then be converted to the filesystem encoding.
