+ length of the sequence, inclusive), a code point represented starting at the
+ given index is computed as follows:
+
+ - If the UTF-16 code unit addressed by the index constitutes a well-formed
+ UTF-16 code unit sequence, the computed code point is the scalar value
+ encoded by that UTF-16 code unit sequence.
+
+ - Otherwise, if the index is at least two UTF-16 code units away from the
+ end of the sequence, and the sequence of two UTF-16 code units addressed by
+ the index constitutes a well-formed UTF-16 code unit sequence, the computed
+ code point is the scalar value encoded by that UTF-16 code unit sequence.

+ - Otherwise, the computed code point is the UTF-16 code unit addressed by
+ the index. (This last case catches unmatched surrogates as well as indices

+ (in UTF-16 code units), inclusive. Upon successful return, the index will
+ be updated to address the UTF-16 code unit that is the given

+
+ @param incrementCodePoints
+ the number of code points to move the given *indexUtf16. If non-negative,

+ index. The value must be such that the resulting UTF-16 based index is in

+ value of *indexUtf16. In either case, the computed index must be in the
