I was comparing multiple JS cookie libraries and noticed that client-side generated cookies are correctly created in the browser, but ColdFusion/Tomcat servers haven't been configured for RFC 6265 compliance by default and cookie values are truncated as soon as a the first parenthesis is encountered in a string value.

ie, a(b)c in the client becomes a when read by the server.

In order to get cookie.js to function similar to ColdFusion's CFCOOKIE tag and avoid truncating data (using Tomcat), I've added the following default path setting & encoder function.

cookie.defaults.path = '/';
cookie.utils.encode = function(value){
    return encodeURIComponent(value).replace(/%(23|24|26|2B|3A|3C|3E|3D|2F|3F|40|5B|5D|5E|60|7B|7D|7C)/g, decodeURIComponent).replace(/[\(\)]/g, escape);
};

Are there any potential issues with the above code? (It seems to work in my client/server tests.)

NOTE: I'm posting this here in case other ColdFusion/Java developers consider using this library and encounter this issue.
