我需要用希伯来语添加用户名，

我添加了这个，

add_filter( \'sanitize_user\', \'sanitize_user_with_hebrew\', 10, 3 );

function sanitize_user_with_hebrew( $username, $raw_username, $strict ) {

$username = $raw_username;
$username = wp_strip_all_tags( $username );
$username = remove_accents( $username );
// Kill octets
$username = preg_replace( \'|%([a-fA-F0-9][a-fA-F0-9])|\', \'\', $username );
$username = preg_replace( \'/&.+?;/\', \'\', $username ); // Kill entities

// If strict, reduce to ASCII for max portability.
if ( $strict ) {
    $username = preg_replace( \'|[^a-z0-9א-ת _.\\-@]|i\', \'\', $username );
}

$username = trim( $username );
// Consolidate contiguous whitespace
$username = preg_replace( \'|\\s+|\', \' \', $username );

/**
 * Filter a sanitized username string.
 *
 * @since 2.0.1
 *
 * @param string $username     Sanitized username.
 * @param string $raw_username The username prior to sanitization.
 * @param bool   $strict       Whether to limit the sanitization to specific characters. Default false.
 */

return $username;
}

我的网站是希伯来文的。

谢谢
