Return whether a bounded string contains valid UTF-8.

bool
isValid(
char const** invalidString,
char const* string,
size_type length);Return true if the specified string having the specified length (in bytes) contains valid UTF-8, 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, and string may be null if 0 == length (see {Empty Input Strings}).
true if string is valid UTF-8, and false otherwise
| Name | Description |
|---|---|
| invalidString | if non-null, set to after the last valid code point |
| string | UTF-8 byte sequence (need not be null-terminated) |
| length | length of string in bytes |
