~~~ruby
fname = '���������'
File.write(fname, '')
p File.exist?(fname)
$stdin.reopen(fname, 'r')
~~~

It fails with `Errno::ENOENT` on Windows even though the file exists and is readable. It's caused by using `freopen()` (https://github.com/ruby/ruby/blob/v2_2_2/io.c#L6765). A wrapper that converts to UTF-16LE and then calls `wfreopen()` has to be added to `win32/win32.c`.
