json class converts encoding and strings not appeared correctly

[seco]

Hi

im newbie to php and i have a problem

 

im using mx ajax toolbox ok this is not the problem.

the generated files really awesome

it uses ajax panels for ajax requests without any efforts and works with english text correctly but with non-english text it retireves data and it appeared correctly but when i save it it obfuscate the characters as utf-8 encoded but i want to use my local encoding

i found that it uses json class to encode strings to utf-8 and so it saves it as utf-8 encoded

my question is how to save this data as my local encoding?

 

thanks in advance.
