Re: Relaxing Zope id rules for Zope 4 / Plone 5

Hi Wichert.

Errors occuring may not occur in Plone or Zope itself,
they might even not occur in python itself.

But they might occur on another system which communicates 
with Plone over http
and does itself not support utf-8 urls correctly.

I recently had a similar problem regarding Filenames with whitespaces.

There is a (non open source) cms I'm working  where users can upload files.

These files are fetched by a worker on a different host and converted to a different format.

It showed up that on the worker it wasn't possible to distinguish if the filename contained whitespaces or
underscores.


+1 for making the utf-8 url feature a non default configurable option in Zope/Plone.

Best regards

Hans-Peter Locher

For example my local test site has a URL which looks like http://localhost:8080/Pløne/ in my browser but it really is http://localhost:8080/Pl%C3%B8ne/ . To get there Zope uses urllib.quote() internally, for example in the implementation of the absolute_url() method.
