:mrdocs:

Advance past 0 or more consecutive Unicode code points at the beginning of the specified `string` having the specified `length` (in bytes), until either the specified `numCodePoints` or `length` bytes have been traversed (whichever occurs first), and return the number of Unicode code points traversed. Set the specified `*result` to the address of the byte immediately following the last code point traversed, or to `string` if `length` or `numCodePoints` is 0. `string` need not be null‐terminated and can contain embedded null bytes, and `string` may be null if `0 == length` (see {Empty Input Strings}). The behavior is undefined unless the initial `length` bytes of `string` contain valid UTF‐8 and `0 <= numCodePoints`. Note that the value returned will be in the range `[0 .. numCodePoints]`. Also note that `string` may contain less than `length` Unicode code points.
