Note about encoding of _br_uid_2 cookie is misleading

"The _br_uid_2 cookie is already encoded"

The cookie is encoded if you read it via document.cookies; however any decent framework will read the cookie value and decode it — much of the time the developer has the cookie, it is unencoded. Documenting what the encoded & decoded forms look like would help identify which case one has, and then how to convert to the encoded form would be useful. I figured this out, but the comment actively opened questions that I would otherwise have answered correctly without trying.
