looking for js library for formatting string to match json requirments

Question

I'm using jQuery ajax to send updates from the client's browser to my server,
I noticed that there is some characters that JSON doesn't support,
and in order to send them, i need to add additional \ in front of each.

This characters are well documented at json.com:

_{(source: json.org)}

I'm not so good at javascripting (i'm new in this area),
So i wonder if there is any already made function that takes a string and formats it to fit this requirement?

iv'e searched the web but couldn't find any javascript solution for this..

Thanks in advance, Eitan.

Solved! i spent too much time on this @$!

I found that the JSON.stringify indeed take care of the special characters.
The problem was in the way that i used to structure the data...
I did it like:

blah = JSON.stringify( { a: "1" } );
$.ajax({
         type: "POST",
         url: "page.aspx/MethodName",
         data: "{ paramName: '" + blah + "'}",
         contentType: "application/json; charset=utf-8",
         dataType: "json"});

To fix this, i just did:

//nesting the param name in the data structure passed to stringify:
blah = JSON.stringify( { paramName : { a: "1" } } ); 
    $.ajax({
             type: "POST",
             url: "page.aspx/MethodName",
             data: blah,
             contentType: "application/json; charset=utf-8",
             dataType: "json"});

Thanks for everyone who tried to help me solve this..
