You and I brainstormed this a few months ago. I think this was on the
list. I think that, for starters, we would arrange that all Zope 3
views used in Zope 2 would get unicode input. If you like, I can try
to find this discussion. :)
Ah, right, that is far less scary, indeed. Your post somehow gave me the
impression you wanted to change the way current Zope 2 does things, but
if you limit yourself to what happens with Zope 3 stuff in Zope 2, it's
In fact Five already has hacks to make sure that unicode enters
Five-generated forms. Replacing these hacks with something solid would
Anyway, in some basics, Zope 2 does have an approach to unicode for
*output* that's fairly similar to Zope 3's: if you use unicode strings
your entire output (including page templates) will be unicode (if you
don't mix with non-unicode non-ascii strings..). Then the response
encoding setting is read and everything is transformed once to unicode
text. Silva uses this. It also struggles to make sure all its input is
transformed to unicode (among other ways using Formulator).
In Plone, the situation is quite different -- its
PlacelessTranslationService monkeypatches into the page template
engine and puts in ways so that you can mix UTF-8 and unicode strings
together. This then goes on to break assumptions of code that uses the
page template engine in a unicode-pure environment (which is what
happened to Silva).
I'm not suggesting this is easy. We may have some messy deprecation
and backward compatibility code. But we *do* need to solve this problem
eventually, and the solution doesn't get any closer without taking steps.
Yes. I'm optimistic about being able to do this for Five-related stuff.
If this is eventually going to be people's main development system, then
we can basically say we've solved the important unicode issues.
What I'm worried about doing this for old code, but some steps will
probably become clear during the brainstorming session. Migration tools
that turn strings in the ZODB into unicode ones magically (with the
ability to spell out exceptions and encoding)? Tricky...
