++/*
++ * The utf8_check() function scans the '\0'-terminated string starting
++ * at s. It returns a pointer to the first byte of the first malformed
++ * or overlong UTF-8 sequence found, or NULL if the string contains
++ * only correct UTF-8. It also spots UTF-8 sequences that could cause
++ * trouble if converted to UTF-16, namely surrogate characters
++ * (U+D800..U+DFFF) and non-Unicode positions (U+FFFE..U+FFFF). This
++ * routine is very likely to find a malformed sequence if the input
++ * uses any other encoding than UTF-8. It therefore can be used as a
++ * very effective heuristic for distinguishing between UTF-8 and other
++ * encodings.
++ *
++ * I wrote this code mainly as a specification of functionality; there
++ * are no doubt performance optimizations possible for certain CPUs.
