Comment 1 for bug 304456

I've done some debugging of my own, which reveals that the exception for me occurs in:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd7 in position 0: ordinal not in range(128)
> /media/sdb1/debug-singing/collective.dancing/trunk-buildout/eggs/zope.i18n-3.6.0-py2.4.egg/zope/i18n/__init__.py(161)replace()
-> return unicode(mapping.get(param1 or param2, whole))

the piece of code is:

(Pdb) 156 u'This is ${name}'
157 """
158
159 def replace(match):
160 whole, param1, param2 = match.groups()
161 -> return unicode(mapping.get(param1 or param2, whole))
162
163 if not text or not mapping:
164 return text
165
166 return _interp_regex.sub(replace, text)

and I can confirm this happens only when the title is set with hebrew text
