UnicodeDecodeError saving Page Template

[Yury Don]

We user koi8-r enconding in zope. management_page_charset property set to "koi8-r".
After instaling zope 2.10.2 we added environment variable ZPT_PREFERRED_ENCODING="koi8-r" and overrides.zcml in /Products/PageTemplates with ReplacingUnicodeEncodingConflictResolver.
Rendering of page templates works fine, but when i try to change page template with cyrillic charactres in text or title, I getting an error:
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 0-3: invalid data
The error is in lines 193-194 of /Products/PageTemplates/ZopePageTemplate.py
        # The ZMI edit view uses utf-8! So we can safely assume
        # that 'title' and 'text' are utf-8 encoded strings - hopefully

        self.pt_setTitle(title, 'utf-8')
        text = unicode(text, 'utf-8')
Indeed The ZMI edit view uses utf-8 only if management_page_charset not available.
Replacing string
       self.pt_setTitle(title, 'utf-8')
       text = unicode(text, 'utf-8')
to
        text, encoding = convertToUnicode(text,
                                         content_type,
                                         preferred_encodings)
       self.pt_setTitle(title, encoding)
solved the problem.
Diff file fo ZopePageTemplate.py attached.

Could you please work on a unittest?

I tried to reproduce that once again (using latin as encoding, sorry, I have no russian setup)...works for me. If you want this fixed, we need a unittest. Otherwise the report will remain open and untouched.
