In many places, CMFSetup exports and imports things like titles and
descriptions. For instance, for the workflow states and transitions.
These fields can often, outside the USA, contain non-ascii strings.
How do we export and reimport them ?

1. We can export by converting them to unicode, and the ZPT will
render that as UTF-8. Which charset do we assume ? Anything better
than "locale.getlocale()[1] or 'latin1'" ?

2. When importing, do we set the values (attributes) as unicode, or
do we try to re-convert to the above charset...

I think, we should keep all text as Unicode -- even in
english speaking environments....

If this is not an option, the external format should use Unicode
and some configuration parameter (Plones uses "site_encoding")
converts from/to the external Unicode.

There's actually little problem for the export, we can always infer an encoding from somewhere, be it locale.getlocale or site_encoding or default_encoding or something like that, and export as UTF-8, the native XML encoding.

The problem is on import, you don't really know if a non-ascii string should be stored as unicode or as an encoded str. And the software may break if it gets something it doesn't expect...

Our immediate problem was with workflow transition descriptions, which contained accents. In that case, the DCWorkflow code does str() anyway so I know it's a string, but I wanted a general opinion.

I can't find the time to fix that before the next 1.5.2 release in any case, so I'll do that later.
