I would recommend encoding the value you are putting into the cookie so that the value you are storing can contain semi-colons.

You may want to look at encodeURIComponent and decodeURIComponent.

An example

window.encodeURIComponent(';'); // results in %3B

You need to escape the string you want to store in the cookie

eg: escape('a;') will give "a%3B"
