[Zope] UnicodeDecodeError

[Stefan Loidl]

Hi Yuri,

does this error occur with all browsers? I once had a similar issue
that was caused only by some browsers because they do not send a
HTTP_ACCEPT_CHARSET header.

Maybe the following bug reports helps you in solving the issue:
https://bugs.launchpad.net/zope2/+bug/160968

I'm using a workaround similar to that in the bug report in my
environment (Zope 2.13.13 and a mixture of utf-8 and iso8859).
Without the workaround the issue does still occur for me.

Greetings,
Stefan
