Hi,
because Zope 2.10.2+ will use unicode as internal representation for
page templates I am currently checking the options to get rid of
UnicodeDecodeErrors for Zope 2.11 by providing some more intelligent
conversion of non-unicode content. Basically I want if the content
returned by expressions within a page template if unicode or
non-unicode. If it is non-unicode it would be converted based on some
policy (to be specified) to unicode. This would avoid any kind of
UnicodeDecodeError (hopefully).
This there a central place in the ZPT code were the evaluated
expressions are inserted into the rendered HTML or some internal
datastructure used for rending the ZPT? I just need to know where to
look at but I have no idea so far :-)
This kind of automagic unicode error defeating logic scares me. With
Silva, we have a significant Zope 2 application that already takes care
to output unicode to the page template engine. For a while we were using
PlacelessTranslationService which has some hacks in place to do
automagic conversion from unicode to an encoding. Granted this is the
opposite direction than you are proposing, and my intuition is that your
direction may be less scary, but I'm still scared. Not having unicode
errors can make debugging of pure-unicode applications harder. Bugs
sneak in pretty easily and you end up with non-pure content.
I'd therefore like it if there were a way, application-root specific, to
turn off any auto-conversion behavior. Do you think that would be possible?

Martijn
