*
* Upon return, \a bcslen is modified to the actual number of bytes written to
* \a bcs excluding the terminating null; \a ucslen is modified to the number of
* wide characters converted.

* You may pass #STIX_NULL for \a bcs to dry-run conversion or to get the
* required buffer size for conversion. -2 is never returned in this case.

* - -1 on no or partial conversion for an illegal character encountered,
* - -2 on no or partial conversion for a small buffer.
