The proper fix, IMO, is to have writexml accept an encoding argument,
and, by default, write the output as UTF-8. Then there is no need for

In any case, emitting ü and € in XML is wrong: you cannot
use them unless your document type provides them - you should not
assume that all XML files use the HTML DTD.
