[Help] zTeam 6.3 (Repack) - more then 3 hebrew charcters in chat is censored

Hello Dear MuOnline Community,
I'm working on zTeam 6.3 files and i've ran into a problem i cant fix.
My main language in hebrew so i want to be able to write in hebrew in game
and i can write in hebrew but only up to 2 charcters if i write 3+ charcters i'm getting censored.
I've turned "bad words filter" off just in case, but still didn't helped.
The only thing that i've found making some impact is "ProtocolFilter.dat" file which contains some numbers which i dont understand and i have no idea what's going on in that file.

If the client wasn't able to show hebrew charcters at all i wouldn't even bothered but since it can show 2 charcters i know for sure that it's possible to make hebrew work with this server\client files.

This is what i'm getting when i'm trying to write more than 2 charcters.

Code:

*censorý

Also when trying to write more then 2 charcters GS is outputting this :

And the number of question marks is equal to the number of hebrew charcters that i write.

If someone have even a little clue of what it could be please let me know.

Thanks in advanced, Afik!
