-// Note: below we pass invalid UTF-8 to the tIn and tNotIn transformers as is.
-// This is done for various reasons:
-// - To retain the semantics of the Nop transformer: if input is passed to a Nop
-//   one would expect it to be unchanged.
-// - It would be very expensive to pass a converted RuneError to a transformer:
-//   a transformer might need more source bytes after RuneError, meaning that
-//   the only way to pass it safely is to create a new buffer and manage the
-//   intermingling of RuneErrors and normal input.
-// - Many transformers leave ill-formed UTF-8 as is, so this is not
-//   inconsistent. Generally ill-formed UTF-8 is only replaced if it is a
-//   logical consequence of the operation (as for Map) or if it otherwise would
-//   pose security concerns (as for Remove).
-// - An alternative would be to return an error on ill-formed UTF-8, but this
-//   would be inconsistent with other operations.

-// If returns a transformer that applies tIn to consecutive runes for which
-// s.Contains(r) and tNotIn to consecutive runes for which !s.Contains(r). Reset
-// is called on tIn and tNotIn at the start of each run. A Nop transformer will
-// substitute a nil value passed to tIn or tNotIn. Invalid UTF-8 is translated
-// to RuneError to determine which transformer to apply, but is passed as is to
-// the respective transformer.
