When a request submitted to the server contains non-ascii characters,

This is a bug in Mulberry - its not sending utf-8 as it should, but instead iso-8859-1 or something. I guess I will kick the Mulberry person and get them to fix it :-)

Hi Cyrus,

thanks for your quick response.

I'm not completely sure, but I don't think it's a bug in Mulberry. I recoded Mulberry's request myself and could not find any problems. Then I tried Mozilla Sunbird and had the same problem: pure ASCII requests work fine, umlauts in the SUMMARY (or elsewhere?) raise the same error on the server. The encoding of the same three umlauts results in the same six UTF-8 octets.

Here is the "Ethereal Follow TCP Stream" output of both requests. (Sorry for any inconvenience due to this message's "flowed" format.) Note the different Content-Type values and the different line breaks (0x0a in Mulberry, 0x0d 0x0a in Sunbird), though the raised error is the same.

I do not yet have an iCal3 to play with. Can you suggest any other clients I could try and compare?
