 Look at the first line of the output from `d.rast --interface-
 description`. The encoding= parameter is probably something Windows-
 specific like "CP932". In which case, we may need to use something other
 than locale_charset() (e.g. bind_textdomain_codeset() with NULL for the
 codeset parameter), or even convert the text to UTF-8.

 Except ... GUI.!ParseCommand() assumes that the text is in the locale's
 encoding and is explicitly converting it to UTF-8. But it doesn't change
 the encoding= in the XML header, which will still contain the locale's
 encoding (maybe this pre-dates r17034 being back-ported?).

 The fact that it's xml.sax.parseString() which is failing rather than the
 ".decode(enc)" in the argument suggests that Python understands the
 encoding, so it may suffice to do something like:

 {{{
 - ... .decode(enc).encode("utf-8") ...
 + ... .decode(enc).split('\n',1)[1].replace('', '<?xml version="1.0"
 encoding="utf-8"?>\n', 1).encode("utf-8") ...
 }}}

 The situation is complicated by the fact that 6.5/7.0 has abandoned
 xml.sax in favour of xml.etree.!ElementTree.
