查找:
PHP 代码:

header( "Content-Disposition: attachment; filename=\"{$attach['attach_file']}\"" );  

替换为：
PHP 代码:

/* attach name covertCharsets */ 
//    header( "Content-Disposition: attachment; filename=\"{$attach['attach_file']}\"" ); 
header( "Content-Disposition: attachment; filename=\"" . @iconv( "utf-8", $charset, $attach['attach_file'] ) . "\"" );  

注：使用了iconv函数

也可以使用urlencode，缺点是空格变成了+号
PHP 代码:

header( "Content-Disposition: attachment; filename=\"" . urlencode($attach['attach_file']) . "\"" );
