My XML markup includes an &mdash; in the <title>.  This looks fine in HTML, but 
idnits 2.16.05 finds non-ascii utf-8 e28084 in the txt file.

I fixed the problem by adding the line

   text = text.replace(u'\u2014', u'-')  # Replace &mdash; EM DASH with HYPHEN-MINUS

to file $PYTHON/site-packages/xml2rfc/writers/text.py immediately before line

   text = text.replace(u'\u00A0', u' ')

Could this be made a permanent change?

Perhaps there are other character entities which could profit from such 
replacement.
