Description:
------------
We work with OpenLDAP 2.1.22 and PHP 4.3.8
I'm working in a set of applications to manage our LDAP directory.
We archive into the LDAP information about users, and need to save spanish characters, such as "?", "?",...
So when I try to add an entry into the ldap, I apply "utf8_encode" to some attributes. By the moment these attributes are: 'cn', 'sn' and 'gecos'.
When this happens, I have 2 problems:
1. In 'sn' there use to be 2 words, first surname and second surname, and after apply utf8_encode, it deletes the second surname.
2. When I try to add the entry into the ldap, I get an error and it can't be done

Any idea?

Reproduce code:
---------------
The code is this:

$info['uid']=$uid;
$info['cn']=utf8_encode($cn);
$info['sn']=utf8_encode($sn);
$info['userPassword']="{MD5}".base64_encode(pack("H*",md5($clave)));
$info['gecos']=utf8_encode($gecos);
$info['ou']=$ou;
$ds=ldap_connect($servidor);
if($ds) {
	$user="cn=Administrador,o=ou.uvigo.es";
	$r=ldap_bind($ds,$user,$cla);
	if ($r)
	{
		$a?ade= ldap_add($ds,$usuario,$info);
		...
	}
}

Expected result:
----------------
If everything were ok, I would see "Usuario a?adido con ?xito". Instead of that I only get "Invalid syntax". 

Actual result:
--------------
The actual result is:

Warning: ldap_add(): Add: Invalid syntax in /var/www/html/proyecto/crear_usuario.php on line 70
