Makes perfect sense when you put it like that, I guess.
But I woluld never have guessed it from reading the APIdoc...
I would have liked to ad a comment about this in the doc, but that function
seems to be out of order for both FF, and Opera.
Thanks anyway.

"manage_changeProperties" has two usage modes: one for programmatic
use and one for ZMI use. As many other management functions,
it distinquishes between the two mode by checking whether
"REQUEST" is "None". When used from the ZMI, the ZPublisher
passes in "REQUEST" which therefore is not None.
You passed a positional argument to "manage_changeProperties"
which it interprets as "REQUEST". Therefore, it thinks it were
used from the ZMI and uses the "management_charset" (or something
like that) as encoding.
Use "manage_changeProperties(**dict)" instead of
"manage_changeProperties(dict)" to avoid this problem.

That's making more sense :)
I was suspecting something like that.
I should have learned to ignore Andreas Jung's arrogant misreadings last
time. :(
1)
Zope Version: (unreleased version, 2.7.0-based, python 2.3.3, linux2)
2)
A few quick googles was not able to reveal where I can get hold of the
manage_page_charset settings...
3)
No mention of "char" or "encode" in zope.conf

WTF is that?
My guess would be the dict-argument is used in place of
REQUEST and therefore sets some default encoding in
request - which it certainly acquires.
'Hustype' is pure ASCII...this will *always* have the same encoding in
almost all encodings (except in Klingon).
Sorry, I was misreading your posting. But to some degree it looks odd..put
it in the Zope bugtracker otherwise it will be forgotten!

This makes less sense. You're passing an ASCII string which has the same
representation in UTF-8..so why should this be a utf-8 string?
You ask me?
I ask you!
Strange opionion. Again: an ASCII string will *never* mutate to something
else. It's representation in ISO-X, UTF-8 or whatever is *always* the
same as the ASCII representationin addition it is not reproducable.
Another try?
Yes, go ahead and file a bug report to the Zope Collector including a
reasonable description of the problem and a description how to reproduce it.

[Zope] manage_changeProperties has strange side effect on response Content-Type.
This gave me such a headache today, that I thought I ought to mention it.
All my pages normally have a content-type of ISO-8859-1
I have not spent much thought on this, it has just worked nicely like that.
Today I had a page that called a python script, that even when I made it
return an empty string, changed the content-type of my page to utf-8.
I finally tracked it down to this difference:
item.manage_changeProperties({'title':'Hustype'}) gives utf-8.

intact.
