After migrating a Plone 2.5 site to Plone 3, I got a
UnicodeEncodeError when viewing the site.
Apparently the site was configured to use
ISO-8859-15 as the
default character set. However,
FactorySubMenuItem and the title property contains an
ellipsis as unicode
_(u'label_add_new_item', default=u'Add new\u2026')
Rendering a page resulted in this error:

the way, a good tip from
Maurits van Rees.) The funny thing is
that the Plone migration had set the default language from Dutch to
English. Otherwise I would not even have noticed this issue: the
translation for the
label_add_new_item does not contain the
I cannot directly come up with a good reason to not use UTF-8 as the default character set for a Plone site. If you do know a reason, please let me know, I’d love to hear about it! Either way: beware of this issue.
