We define the meaning of mbstate_t as follows:
- In mb -> wc direction, mbstate_t's first byte contains the number of
buffered bytes (in the range 0..3), followed by up to 3 buffered bytes.
See mbrtowc.c.
- In wc -> mb direction, mbstate_t contains no information. In other
words, it is always in the initial state. */
