/// A codec that converts byte arrays to and from percent-encoded (also known as
/// URL-encoded) strings according to [RFC 3986][rfc].
/// [rfc]:
/// [encoder] encodes all bytes other than ASCII letters, decimal digits, or one
/// of `-._~`. This matches the behavior of [Uri.encodeQueryComponent] except
/// that it doesn't encode `0x20` bytes to the `+` character.
/// To be maximally flexible, [decoder] will decode any percent-encoded byte and
/// will allow any non-percent-encoded byte other than `%`. By default, it
/// interprets `+` as `0x2B` rather than `0x20` as emitted by
/// [Uri.encodeQueryComponent].
