zope.formlib.form.Action does not work with Unicode label

[yasusii]

>>> from zope.formlib.form import Action
>>> Action(u'\u9001\u4fe1')
Traceback (most recent call last):

As a workaround for this bug, you can pass the 'name' for the action in addition to the label. E.g.:

  Action(u'\u9001\u4fe1', name='my_action')

Thanks for the report!

The patch solves the wrong problem - labels can be unicode, indeed ASCII is coerced to unicode. hex is used for whitespace. The regex needs updating to cope with unicode. And a test is required.
