If OFFSETS is not NULL, it should point to an array of SRCLEN integers; this
array is filled with offsets into the result, i.e. the character starting
at SRC[i] corresponds to the character starting at (*RESULTP)[OFFSETS[i]],

RESULTBUF and *LENGTHP should initially be a scratch buffer and its size,
or *RESULTBUF can be NULL.
May erase the contents of the memory at RESULTBUF.
If successful: The resulting Unicode string (non-NULL) is returned and its
length stored in *LENGTHP. The resulting string is RESULTBUF if no dynamic
memory allocation was necessary, or a freshly allocated memory block
otherwise.
In case of error: NULL is returned and errno is set. Particular errno
values: EINVAL, EILSEQ, ENOMEM. */
