[JDEV] UTF 8 problems in jabber stream...

[kmq at gmx.at]

Hi,
as most of you know i amd developing my new client using the wxWindows workframe.
App is working fine so far, even UTF-8 conversion worked.

Whatever yesterday i noticed that some UTF-8 data that is sent from 
ns at neutralstone.net to my client causes thw wxString conversion functions to fail 
(including buffer overflow).

First I thought there might be a bug in the wxWindows UTF 8 conversion functions and i 
mailed the developers of wxWindows.
You can follow the discussion here: http://lists.wxwindows.org/pipermail/wx-users/2002-
September/025284.html

if the author is right that would mean that
1. gabber is sending invalide UTF 8 to the server.
2. jabberd does not check the UTF 8 encoded string.

well, one side must be wrong!

could it be that the jabberd has a bug here or is the wxwidnwos author wrong?
