Can you store commas with spaces inside cookies?

Question

I recently played with cookies, and I noticed that when I create one with the value "Hello, World!" I get "Hello":

document.cookie = "testCookie=Hello, World!;";

Interestingly, if I do not add a space to "Hello, World!" , the cookie value will remain as I set it: ("Hello, World!")

document.cookie = "testCookie=Hello,World!;";

My only guess is why this happens because the comma and space “,” end cookies, such as semicolons and spaces, “do.” Is this true, or am I doing something wrong?
