Pity, it is quite useful if you are somewhere that uses UTF-8 SSIDs,
otherwise it's a complete pain to decode to figure out if you're
connecting to the correct network. An alternative would be to filter
ifconfig output through something like this

while(<>) {
        if ($_ =~ m/nwid 0x([0-9a-f]+)\s/) {
                my $hex = $1;
                my $decoded = pack "H*", $hex;
                $_ =~ s/$hex/$hex ("$decoded")/;
        }
        print $_;
}

but it won't validate the characters so best redirect output to a file
and open it in a UTF-8 editor to view it rather than displaying it
directly on a terminal.
