Funky Characters in Log files

[Travis Thornhill]

I know there have probably been a thousand posts on this topic, and I apologize 
in advance for skipping over them and deleting them.
 
I have instances of strange characters in logs, and I'd like to be able to 
print them properly.
 
Here's an example of a few lines:
 
L 06/27/2008 - 18:37:18: "[PLC]tẅistedbiЯdmań<181><STEAM_0:0:########><CT>" 
say "[͇̿L͇̿e͇̿a͇̿r͇̿n͇̿(ٿ)͇͇͇͇̿̿̿̿ ͇̿2͇̿ 
͇͇̿̿(ٿ)͇̿P͇̿l͇̿a͇̿y͇͇̿̿]"

L 06/27/2008 - 18:37:19: "[PLC]tẅistedbiЯdmań<181><STEAM_0:0:########><CT>" 
say "{̲̅O̲̲̲̅̅̅w̲̲̅̅N̲̲̅̅3̲̲̅̅D̲̅}"

L 06/27/2008 - 18:37:38: "[PLC]tẅistedbiЯdmań<181><STEAM_0:0:########><CT>" 
killed "ℓῐᵯӗؐ<197><STEAM_0:0:16680331><TERRORIST>" with "awp"
 
What is this stuff, and where can I begin to look for how to print it properly?
 
Thanks!
