Ceph

Windows CLI arguments use either ANSI (main()) or UTF-16 (wmain()). Meanwhile, Ceph libraries expect UTF-8 and raise exceptions when trying to use Unicode CLI arguments:

  rbd.exe create test_unicode_șțăâ --size=32M
  terminate called after throwing an instance of 'std::runtime_error'
    what():  invalid utf8

The same happens when attempting to log Unicode characters, which in particular affects ceph-dokan while logging Unicode paths.
