Non-ASCII chars, iCal and ZCS

[MacTI]

I just found a major problem between iCal, ZCS, Mail and non-ASCII chars. First I created an event in a local calendar with the following subject :



And I invited my ZCS account and sent out the invitation. The invitation subject is ok when I view it in ZCS Web client :



But things go ugly after I accept the invitation. The answer look like this :



And in the calendar, the event look like this :



So it look like ZCS can't deal with non-ASCII chars in events. One thing I did notice, Mail and iCal seems to use Windows-Latin-1 as the encoding for the invitation :

Subject: =?WINDOWS-1252?Q?_Tes?=
=?WINDOWS-1252?Q?t_accents_=E9=E8=E0=E7=F9=E7?=
X-Mail-Calendar-Part: Yes
Date: Tue, 14 Oct 2008 10:41:26 -0400
X-Mailer: Apple Mail (2.929.2)


--Apple-Mail-9-874950417
Content-Type: text/plain;
charset=WINDOWS-1252;
format=flowed;
delsp=yes
Content-Transfer-Encoding: quoted-printable

But ZCS reply is done in UTF-8 :

Subject: =?utf-8?Q?Accepter:_Test_a?= =?utf-8?Q?ccents_=EF=BF=BD?=
=?utf-8?Q?=EF=BF=BD=EF=BF=BD=EF=BF=BD=EF=BF=BD?=

I guess that's part of the problem?

I can confirm that this problem doesn't appear between Outlook (with the connector) and iCal.
