+ Their unit is an uint16_t (a 2-byte word).
+
+ All functions prefixed with u32_ operate on UCS-4 encoded strings.
+ Their unit is an uint32_t (a 4-byte word).
+
+ All argument pairs (s, n) denote a Unicode string s[0..n-1] with exactly
+ n units.
+
+ All arguments starting with "str" and the arguments of functions starting
+ with u8_str/u16_str/u32_str denote a NUL terminated string, i.e. a string
+ which terminates at the first NUL unit. This termination unit is
+ considered part of the string for all memory allocation purposes, but
+ is not considered part of the string for all other logical purposes.
+
+ Functions returning a string result take a (resultbuf, lengthp) argument
+ pair. If resultbuf is not NULL and the result fits into *lengthp units,
+ it is put in resultbuf, and resultbuf is returned. Otherwise, a freshly
+ allocated string is returned. In both cases, *lengthp is set to the
