Return the number of Unicode code points in the specified string having the specified length (in bytes). 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 string contains valid UTF‐8. Note that string may contain less than length Unicode code points.
