怎么让Wordpress 注册支持中文用户名

sanitize_user在wp_includes/formatting.php中定义,其函数体如下：

function sanitize_user( $username, $strict = false ) {
$raw_username = $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( '/&.+?;/', '', $usernam
e ); // Kill entities

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

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

return apply_filters( 'sanitize_user', $username, $r
aw_username, $strict );
}

$strict = false;

或者注释掉

//$username = preg_replace( '|[^a-z0-9 _.-@]|i', '', $username );

//增加中文注册
function china_login( $username, $raw_username, $strict ) {
if( !$strict )
return $username;
return sanitize_user(stripslashes($raw_username), false);
