 of the four normal forms, known as NFC, NFD, NKFC, NFKD.  These
 transformations involve decomposition and --- for NFC and NFKC --- composition

 A ``stream of Unicode characters'' is essentially a function that accepts an
 @code{ucs4_t} argument repeatedly, optionally combined with a function that
 ``flushes'' the stream.
