It appears to me that I can't have german umlauts (or any other
non-ascii chars for that matter) on buttons, for example ("Ändern"
- with A umlaut - ist german for "Change"):
# -*- coding: utf-8 -*-
...
class MyDisplayForm(form.Form):
...
@button.buttonAndHandler(u'Ändern')
def change(self, action):
self.request.response.redirect('edit')
tons of error msgs:

I get similar errors at runtime (when rendering the form) if I try to
change the title of an existing button:
class AdrEditForm(form.EditForm):
...
buttons=form.EditForm.buttons
# save changes
buttons['apply'].title=u'Änderungen speichern'
this gives me:

Two points to note:
* I don't want to introduce i18n just for the buttons
@button.buttonAndHandler(_(u'Change'))
My app is german only and if I was to introduce i18n I would still
make german the primary language and English the second,
i. e. I would still want
@button.buttonAndHandler(_(u'Ändern'))
* This caused me no problems in formlib, there I could do e. g.
@action(u'Aendern')
def aendern(self, action, data):
self.request.response.redirect('edit')
actions[u'actions.aendern'].label=u'Ändern'
@action(u'Loeschen')
def loeschen(self, action, data):
...
actions[u'actions.loeschen'].label=u'Löschen'
This is the last show stopper of z3c.form for me:
I promise I will stop lamenting about features of formlib
not found in z3c.form once I get this fixed.
Did I overlook something here - some easy workaround maybe?
