[icq-devel] Strange characters in channel 4 messages

I was wondering if anyone knew what the formating characters mean in channel 4
ICBMs (family 0x04, subtype 0x06 and 0x07).  I'm thinking these might carried
over from older ICQ protocol versions, but I'm not sure.  Here's an example
packet:

0030  40 00 ba 9a 00 00 2a 02  aa 1b 00 6c 00 04 00 07   @.º...*. ª..l....
0040  00 00 82 ac 61 ed 92 78  de 02 19 20 00 00 00 04   ...¬aí.x Þ.. ....
0050  08 xx xx xx xx xx xx xx  xx 00 00 00 04 00 01 00   .5611722 2.......
0060  02 00 50 00 06 00 04 20  03 00 00 00 0f 00 04 00   ..P....  ........
0070  00 02 d8 00 03 00 04 3d  1a 7e f2 00 05 00 29 xx   ..Ø....= .~ò...)æ
0080  xx xx xx 0c 00 21 00 fe  4e 61 6d 65 58 58 fe fe   GX...!.þ NameXXþþ
0090  4e 61 6d 65 58 58 58 40  61 61 61 2e 6e 61 6d 65   NameXXX@ aaa.name
00a0  2e 61 61 61 fe 31 fe 00                            .aaaþ1þ.  

Does anyone know what the þ, hexidecimal 0xfe, characters are?  Or what they
mean?  I've seen these in old-style auth requests/replies, urls, etc.  I'm
guessing they're valid characters in any channel 4 IM.

Any help is much appreciated,
Mark
