+/* These work like the printf function family.
+ In the format string:
+ The format directive 'U' takes an UTF-8 string (const uint8_t *).
+ The format directive 'lU' takes an UTF-16 string (const uint16_t *).
+ The format directive 'llU' takes an UTF-32 string (const uint32_t *).
+
+ The prefix (ulc_, u8_, u16_, u16_) indicates the type of the resulting
+ string. The prefix 'ulc' stands for "locale encoded".
+
+ An infix 'v' indicates that a va_list is passed instead of multiple
+ arguments.
+
+ The functions *sprintf have a 'buf' argument that is assumed to be large
+ enough. (DANGEROUS! Overflowing the buffer will crash the program.)
+ The functions *snprintf have a 'buf' argument that is assumed to be 'size'
+ units large. (DANGEROUS! The resulting string might be truncated in the
+ middle of a multibyte character.)
+ The functions *asprintf have a 'resultp' argument. The result will be
+ freshly allocated and stored in *resultp.
+ The functions *asnprintf have 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 length (number
+ of units) of the returned string. In case of error, NULL is returned and
+ errno is set.
