Hi Mat,

we have a known error with Wallace not really handling 
internationalized headers really well, see [1], among other issues that 
have been reported not related to iTip messages.

In your specific case, it is Wallace not being able to write out some 
characters using the json.dumps() that it does, while the data it 
attempts to write out to its spool is not ascii - the default parameter 
/ensure_ascii/ for json.dumps() appears to be set to /True/.

I have been working on this before, but I'm not sure I have the proper 
solution. Basically, I need more test data to throw at my new set of 
functional tests to try to cover this issue.

Kind regards,

Jeroen van Meeuwen
