 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.

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.

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?




item.manage_changeProperties(title='Hustype')   leaves ISO-8859-1 
intact.


see above.



WTF is that?


Your example is just poor.



Now you have been warned :)


Another try?

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.

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.

But this is all looking into the crystal sphere because
I not yet have time to actually look at the source -
otoh it would be of great help if you provide:

1.) the excat zope version
2.) manage_page_charset settings
3.) default encodings set in zope.conf etc.

'Hustype' is  pure ASCII...this will *always* have the same encoding in 
almost all encodings (except in Klingon).

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
