I'm trying to get a product running in Zope 2.12 which I installed in a virtualenv with easy_install. It starts fine and all but when I try to render a piece of ZPT I get this weird error:

After a lot of trial-and-error I managed to figure out that the culprit was this piece of ZPT code: tal:content="structure python:here.getRoot().title_or_id().replace(' ',' ')" Stupid and easy to fix; maybe but what if there are other problems like this?

Likely related to the new ZPT engine since Zope 2.10. Either you deal with this using the unicode conflict resolver of ZPT or ensure that you don't mix up different encodings since ZPT now uses unicode internally. - -aj -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkvcL2IACgkQCJIWIbr9KYzjqACfWQ+7gQO0wO2q3vFzptxvrs5Q 7CoAnRiCa6aTeOqX58GBN9DHubwKkYr1 =myaM -----END PGP SIGNATURE-----

Note: no ' ' in that expression.

Module PythonExpr, line 1, in <expression> UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128)

This says that the title_or_id method is returning a non-ASDII value, which, after the 'replace' method of the string runs, can't be inlined into the template. Try something like: here.getRoot().title_or_id().decode('utf8').replace(' ', ' ')

What's the cause of this? Do I have to set something special up in zope.conf just for Page Templates to not convert 'nbsp;' into '\xa0\xc2'?

Try installing the PDBDebugMode product in your instance and have a look at the offending value "live".
