:mrdocs:

Return the length (in bytes) of the UTF‐8‐encoded code point beginning at the specified `codePoint`. The behavior is undefined unless `codePoint` is the address of the first byte of a valid UTF‐8 encoded character. Note that the value returned will be in the range `[1 .. 4]`. Also note that 1 is returned if `0 == *codePoint` since '0' is a valid 1‐byte encoding.
