/**
 * Finds spans of valid and invalid UTF-8 bytes in a given string.
 *
 * This is a low-level tool to power various UTF-8 functionality.
 * It scans through a string until it finds invalid byte spans.
 * When it does this, it does three things:
 *
 *  - Assigns `$at` to the position after the last successful code point.
 *  - Assigns `$invalid_length` to the length of the maximal subpart of
 *    the invalid bytes starting at `$at`.
 *  - Returns how many code points were successfully scanned.
 *
 * This information is enough to build a number of useful UTF-8 functions.
 *
 * Example:
 *
 *     // ñ is U+F1, which in `ISO-8859-1`/`latin1`/`Windows-1252`/`cp1252` is 0xF1.
 *     "Pi\xF1a" === $pineapple = mb_convert_encoding( "Piña", 'Windows-1252', 'UTF-8' );
 *     $at = $invalid_length = 0;
 *
 *     // The first step finds the invalid 0xF1 byte.
 *     2 === _wp_scan_utf8( $pineapple, $at, $invalid_length );
 *     $at === 2; $invalid_length === 1;
 *
 *     // The second step continues to the end of the string.
 *     1 === _wp_scan_utf8( $pineapple, $at, $invalid_length );
 *     $at === 4; $invalid_length === 0;
 *
 * Note! While passing an options array here might be convenient from a calling-code standpoint,
 *       this function is intended to serve as a very low-level foundation upon which to build
 *       higher level functionality. For the sake of keeping costs explicit all arguments are
 *       passed directly.
 *
 * @since 6.9.0
 * @access private
 *
 * @param string    $bytes             UTF-8 encoded string which might include invalid spans of bytes.
 * @param int       $at                Where to start scanning.
 * @param int       $invalid_length    Will be set to how many bytes are to be ignored after `$at`.
 * @param int|null  $max_bytes         Stop scanning after this many bytes have been seen.
 * @param int|null  $max_code_points   Stop scanning after this many code points have been seen.
 * @param bool|null $has_noncharacters Set to indicate if scanned string contained noncharacters.
 * @return int How many code points were successfully scanned.

		 * The above fast-track handled all single-byte UTF-8 characters. What

		 *
		 * Therefore everything past here is checking those multibyte sequences.
		 *
		 * It may look like there’s a need to check against the max bytes here,
		 * but since each match of a single character returns, this functions will
		 * bail already if crossing the max-bytes threshold. This function SHALL
		 * NOT return in the middle of a multi-byte character, so if a character
		 * falls on each side of the max bytes, the entire character will be scanned.
		 *
		 * Because it’s possible that there are truncated characters, the use of
		 * the null-coalescing operator with "\xC0" is a convenience for skipping
		 * length checks on every continuation bytes. This works because 0xC0 is
		 * always invalid in a UTF-8 string, meaning that if the string has been
		 * truncated, it will find 0xC0 and reject as invalid UTF-8.
