corrupted offline messages containing both ascii and non-ascii chars

[wakeroid@…]

oscar account is always "invisible" (which is ok for me), but when SOME other (mirabilis) client sends me (offline) message - it is corrupted, all non-ascii characters are 0x3f, but ONLY when there are both ascii and non-ascii chars in the message body.

The bug is experienced only with certain clients, e.g. with mirab icq 2003b pro.

The problematic messages are coming through "channel4".

here's a hex dump of what i get for msg "тест test": 3f 3f 3f 3f 20 74 65 73 74

Gaim2 has bug too (you must be invisible and 2003bpro contact must not be in visible list, or you must be offline to recieve offline msg).

2003bpro<->2003bpro conversation under same circumstances goes well.

if the message doesn't contain latin letters - it is recieved fine.
