	 *     false === wp_is_valid_utf8( "\xED\xB0\x80" );   // Surrogate halves.

	 * Replaces ill-formed UTF-8 byte sequences with the Unicode Replacement Character.

	 * Knowing what to do in the presence of text encoding issues can be complicated.
	 * This function replaces invalid spans of bytes to neutralize any corruption that
	 * may be there and prevent it from causing further problems downstream.
	 *
	 * However, it’s not always ideal to replace those bytes. In some settings it may
	 * be best to leave the invalid bytes in the string so that downstream code can handle
	 * them in a specific way. Replacing the bytes too early, like escaping for HTML too
	 * early, can introduce other forms of corruption and data loss.
	 *
	 * When in doubt, use this function to replace spans of invalid bytes.
	 *
	 * Replacement follows the “maximal subpart” algorithm for secure and interoperable
	 * strings. This can lead to sequences of multiple replacement characters in a row.
	 *
	 * Example:
	 *
	 *     // Valid strings come through unchanged.
	 *     'test' === wp_scrub_utf8( 'test' );
	 *
	 *     // Invalid sequences of bytes are replaced.

	 *     '.�.' === wp_scrub_utf8( ".\xC0." );              // C0 is never valid.
	 *     '.�.' === wp_scrub_utf8( ".\xE2\x8C." );          // Missing A3 at end.
	 *     '.��.' === wp_scrub_utf8( ".\xE2\x8C\xE2\x8C." ); // Maximal subparts replaced separately.
	 *     '.��.' === wp_scrub_utf8( ".\xC1\xBF." );         // Overlong sequence.
	 *     '.���.' === wp_scrub_utf8( ".\xED\xA0\x80." );    // Surrogate half.
	 *
	 * Note! The Unicode Replacement Character is itself a Unicode character (U+FFFD).
	 * Once a span of invalid bytes has been replaced by one, it will not be possible
	 * to know whether the replacement character was originally intended to be there
	 * or if it is the result of scrubbing bytes. It is ideal to leave replacement for
	 * display only, but some contexts (e.g. generating XML or passing data into a
	 * large language model) require valid input strings.
