encoding ascii data for xml

I have a large amount of data in a postgresql database with the
encoding of SQL_ASCII. Most recent data is UTF-8 but data from
several years ago could be of some unknown other data type. Being
honest with myself, I am not even sure that the most recent data is
always UTF-8-- data is entered on web forms and I wouldn't be
surprised if data of other encodings is slipping in.
Up to the point I have just ignored the problem-- on the web side of
things everything works good enough. But now I am required to stuff
this data into xml datasets and I am, of course, having problems. My
preference would be to force the data into UTF-8 even if it is
ultimately an incorrect encoding translation but this isn't working.
The below code represents my most recent problem:
dom = xml.dom.minidom.parseString( "<test>%s</test>" %
chr(3) is the ascii character for "end of line". I would think that
trying to encode this to utf-8 would fail but it doesn't-- I don't get
a failure till we get into xml land and the parser complains. My
question is why doesn't encode() blow up? It seems to me that
encode() shouldn't output anything that parseString() can't handle.
Sorry in advanced if this post is ugly-- it is through the google
groups interface and google mangles the entry sometimes.
