The released version of that module does not have that bug:

http://svn.zope.org/Zope/tags/2.10.0/lib/python/Products/PageTemplates/Expression.py

Are you sure you are running 2.10.0?

I would probably just bring the affected templates up in the 2.6 ZMI and
 cut and paste their text across into the 2.10 site (to get the charset
