.utf_decode(str) ⇒ Object

From en.wikipedia.org/wiki/Percent-encoding: The generic URI syntax mandates that new URI schemes that provide for the representation of character data in a URI must, in effect, represent characters from the unreserved set without translation, and should convert all other characters to bytes according to UTF-8, and then percent-encode those values. Also sometimes JavaScript encode() function (deprecated) is being used; this uses %uXXXX encoding for UTF-8 chars
