Cant pass non latin characters in ajax call with jQuery

[eluser]iceuser[/eluser]
I am trying to echo non-latin characters via ajax call in jQuery and it fails to echo them.

it returns nothing but when i enter english characters for example, it shows them correctly...

The weird thing is that it was working since some days ago but suddenly it stopped and i cant figure out why.


Charset is utf8 as also defined in head of html.
