QuackyardURL Encoder & Decoder
Percent-encode text for URLs, decode it back, and take a URL apart into its pieces.
As one value in a URL
Escaped the way encodeURIComponent does: the marks that mean something in a URL, like &, = and /, become escapes too.
As a whole URL
Escaped the way encodeURI does: the marks that shape the URL itself, like ://, ? and &, stay readable.
