Fix support for Unicode volume names

Browse Source 
It is possible to create a Unicode volume from the command line,
but it cannot be manipulated by name for operations such as delete.
This is because the find_resource function tries to match the
Unicode string to a regular byte string, and a UnicodeWarning is
issued, failing the match.  Fix by decoding the Unicode name when
trying to match.

Fixes bug 1065275.
