    giscanner: remove unneeded encode('utf-8').decode('utf-8') roundtrip
    
    line is a unicode() instance, xml.sax.saxutils.escape() does
    nothing more than call a couple of replace() methods on said
    unicode() instance so it makes little sense to encode line
    into a str() and decode the escaped result back into a unicode().
