lucene_utf8towcs calls lucene_utf8towc for every character; the
comment on the function is this:

 * lucene_utf8towc:
 * @p: a pointer to Unicode character encoded as UTF-8
 * Converts a sequence of bytes encoded as UTF-8 to a Unicode character.
 * If @p does not point to a valid UTF-8 encoded character, results are
 * undefined. If you are not sure that the bytes are complete
 * valid Unicode characters, you should use lucene_utf8towc_validated()
 * instead.
 * Return value: the resulting character

The call to doc->Add actually expects a TCHAR, so if your utf8 to
utf16 conversion can produce a TCHAR, then that's all that would be
necessary I think.
