`isValid` overloads

== Synopses

Declared in `<bdlde_utf8util.h>`

Return `true` if the specified `string` contains valid UTF‐8, and `false` otherwise. `string` need not be null‐terminated and can contain embedded null bytes.

Return `true` if the specified `string` contains valid UTF‐8, and `false` otherwise. `string` is necessarily null‐terminated, so it cannot contain embedded null bytes.

Return `true` if the specified `string` having the specified `length` (in bytes) contains valid UTF‐8, and `false` otherwise. `string` need not be null‐terminated and can contain embedded null bytes, and `string` may be null if `0 == length` (see {Empty Input Strings}).

Return `true` if the specified `string` contains only valid UTF‐8 characters, and `false` otherwise. If `string` contains invalid UTF‐8, load into the specified `invalidString` the address of the byte after the last valid code point traversed; `invalidString` is unaffected if `string` contains only valid UTF‐8. `string` need not be null‐terminated and can contain embedded null bytes.

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.
