UTF8 data

When you're using UTF8 data, you may run into the "Wide character in print" warning. To fix that in 5.8+, do the following:

my $db = DBM::Deep->new( ... );
binmode $db->_fh, ":utf8";

In 5.6, you will have to do the following:

my $db = DBM::Deep->new( ... );
$db->set_filter( 'store_value' => sub { pack "U0C*", unpack "C*", $_[0] } );
$db->set_filter( 'retrieve_value' => sub { pack "C*", unpack "U0C*", $_[0] } );

In a future version, you will be able to specify utf8 =gt 1 and "" in DBM::Deep will do these things for you.
