Hello.
My grids works fine time ago…(MYSQL, using the php mysql extension) but i update my wamp and now the mysql is deprecated, i try to use Mysqli and put in my code:

$db_conf = array();
$db_conf["type"] = "mysqli";
$db_conf["server"] = "localhost"; // or you mysql ip
$db_conf["user"] = "kkkkk"; // username
$db_conf["password"] = "kkkkkk"; // password
$db_conf["database"] = "kkkkkk"; // database

My database is utf-8 (utf-8-spanish)

If a table contains numeric values the grid works fine, but, if my table contains special chars, like Ñ, á, é, … etc… when load te grid appear "Loading" and no show any data…

The line:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
is in my .html code.

Thanks… and sorry for my poor english.
