I'm really asking whether this declaration is in the internal or in
the external DTD subset.
However, I'm also surprised that you declare mdash as —: This
character is a control character, END OF GUARDED AREA (EPA), and
I don't know why you would associate that with the name mdash...
That your operating system uses byte 151 to represent EM DASH in a
certain code page is irrelevant for XML, XML is based on Unicode, not
code page 1252.

No. 8212 *is* the Unicode number for EM DASH. The error message just
means that you are trying to convert a Unicode string into ASCII (as a
side effect of the print statement), and that ASCII does not support
the EM DASH. Try
instead, if your terminal uses that character set.

I'd say there are several problems at work. The traceback you report says
so I would say that you are *not* using PyXML at all (first problem).
With that version, you will have problems to process entity references
in the SAX application, unless they are in the internal subset (second
You seem to have a misunderstanding of how character references work
in XML, and how they are (not) related to your operating system's
encoding (third problem).
