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.

What do you mean by "some characters JSON.stringify does not like"? `JSON.stringify` converts an object to a JSON string. It may contain `\uHHHH` (where `H`s are hexadecimal numbers), but that is by design. — Lekensteyn, Sep 11 '12 at 17:22

Why do you need to add another `\`? Please provide an example of what you have and what you want to reach. — Lekensteyn, Sep 11 '12 at 17:24

@Lekensteyn - what do you mean? you want me to supply some source code? — Eitan H.S., Sep 11 '12 at 17:33
@jeffery_the_wind - it adds escape to the standart special chars, but what about the unicode chars?.. — Eitan H.S., Sep 11 '12 at 17:36
@jeffery_the_wind - not the regular, but the unicode control characters (from \u0000 to \u001F) — Eitan H.S., Sep 11 '12 at 17:48
@user1179861 `JSON.stringify("\01") == '"\\u0001"'` (displayed as `\u0001`) on Firefox 15.0.1. What else would you expect? — Lekensteyn, Sep 11 '12 at 19:33

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..
