"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.
