:mrdocs:

Return `true` if the specified `string` contains valid UTF‐8, and `false` otherwise. If `string` contains invalid UTF‐8, load into the specified `invalidString` the address of the beginning of the first invalid UTF‐8 sequence encountered; `invalidString` is unaffected if `string` contains only valid UTF‐8. `string` is necessarily null‐terminated, so it cannot contain embedded null bytes.
