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. * $invalid = "the byte \xC0 is never allowed in a UTF-8 string."; * "the byte \u{FFFD} is never allowed in a UTF-8 string." === wp_scrub_utf8( $invalid, true ); * 'the byte � is never allowed in a UTF-8 string.' === wp_scrub_utf8( $invalid, true ); * * // Maximal subparts are replaced individually. * '.�.' === 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 * Once a span of invalid bytes has been replaced by one, it will not be possible * to know whether the replacement character was originally intended to be there * or if it is the result of scrubbing bytes.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. * * @since 6.9.0 * * @see https://www.unicode.org/versions/Unicode16.0.0/core-spec/chapter-5/#G40630 * * @param string $text String which is assumed to be UTF-8 but may contain invalid sequences of bytes. * @return string Input text with invalid sequences of bytes replaced with the Unicode replacement character. */ function wp_scrub_utf8( $text ) { /* * While it looks like setting the substitute character could fail, * the internal PHP code will never fail when provided a valid * code point as a number. In this case, there’s no need to check * its return value to see if it succeeded. */ $prev_replacement_character = mb_substitute_character(); mb_substitute_character( 0xFFFD ); $scrubbed = mb_scrub( $text, 'UTF-8' ); mb_substitute_character( $prev_replacement_character ); return $scrubbed; } else : /** * Fallback function for scrubbing UTF-8. * * @ignore * @private * * @since 6.9.0 */ function wp_scrub_utf8( $text ) { return _wp_scrub_utf8_fallback( $text ); } endif; if ( _wp_can_use_pcre_u() ) : /** * Returns whether the given string contains Unicode noncharacters. * * XML recommends against using noncharacters and HTML forbids their * use in attribute names.
