Your doing things triple-time, which is this time not even half as good:
The
f=codecs.open("tt.xml","r","utf8")
gives you a file that will return unicode objects when reading. And
fwrap=codecs.EncodedFile(f,"ascii","utf8")
will wrap a normal, non-encoding-aware file to become an encoding aware
one. The result is that reading reading from the former already yields a
unicode object that is passed to the second wrapper. It will silently
pass the unicode-object - but it's useless.
And then you try and pass that unicode object of yours to the minidom.
But guess what, the minicom parser expects a (byte) string, as it reads
the mandatory xml encoding header and will decode the contents itself.
So, the passed unicode object is converted to a string beforehand,
yielding the exception you see.
Just don't do any fancy encoding stuff at all, a simple
rrr=xml.dom.minidom.parseString(open("tt.xml").read())
should do.
