// Percent encoding and decoding of slices.
// Transforms arbitrary strings into safe-for-transmission strings by using
// variants of percent encoding (RFC 3986).
// Two major variants are supplied: one that strictly matches URL encoding,
//   and another which applies percent encoding only to non-http2 header
//   bytes (the 'compatible' variant)

  URL,
  // Flags ascii7 non-control characters excluding '%' as unreserved bytes for
  // the percent encoding routines
  Compatible
};

// Percent-encode a slice, returning the new slice (this cannot fail):
// unreserved_bytes is a bitfield indicating which bytes are considered
// unreserved and thus do not need percent encoding

// If a % triplet can not be decoded, pass it through verbatim.
