Bad news. That will cause all management form submissions to encode strings in
utf8. 99% of the methods to which the strings are being submitted will not be
expecting this, and will corrupt characters whose unicode code point is >127.
If you have a ZMI form that *is* expecting this then you need to make some
other changes to avoid breakage. Essentially just adding :utf8: marshalling
tags, possibly some :strings: and :ustring: too.
(yes, this sucks. The problem is that browsers dont specify the character
encoding used in form submissions. At some point we need to discuss the way
forward on this issue....)

Even more bad news. Suppose a dtml page it not yet prepared to handle unicode
(because it hasnt had the changes described above) but it 'accidentally'
encounters a unicode attribute. This happens often in the ZMI when objects
have a unicode 'title', because many products render the title attribute of
*other* objects. We cant force the response to utf8 because this will cause
the same breakage described above.

obviously. ;-)

the manage_properties page that Arnar Lundesgaard has been working with is a
good example. It switches between latin-1 and utf-8 automatically depending
on whether any unicode properties have been defined. (to support *really* old
browsers that dont understand utf8)
