Censor Cirillic

I think you could set mbstring.func_overload to 2 in your php.ini to fix that. not entirely sure though.

Will fix it in the code aswell though.

EDIT: Uploaded a patch file. see attachment.

You can apply it with the patch command (preinstalled in most linux environments https://savannah.gnu.org/projects/patch/)

go to your gsm directory and:

patch -p1 < fixcensor.txt (.txt instead of .patch or .diff ending because of file upload restrictions.)
