Encode broke on PHP through Ajax with jQuery

To simplify what is happening, I'm trying to send the string "Técnico" to PHP, and it is seen as "Técnico" on $_POST var.

The error is on this project alone. I have another 3 projects running on Apache2(same /var/www folder) and they don't present this problem.

Now, the complete way the data goes.

jQuery:

$.ajax({
    url: "config/inserirCargo.php",
    type: 'POST',
    data: {
        titulo: $("#titulo").val()

    },
    success: function(data) {
        $("#cargo").html(data); 
    },
    contentType: 'application/x-www-form-urlencoded; charset=UTF-8' // Tried with and without
});

jQuery Response:

PHP:

var_dump($_POST['titulo']);
die();

My HTML already has the meta tag.

meta http-equiv="Content-Type" content="text/html; charset=utf-8"

And I've already tried these solutions alone and together:

1. AddDefaultCharset UTF-8 - on .htaccess


2. ini_set('charset', 'UTF-8'); - on php file



3. header('Content-Type: text/html; charset=utf-8'); - on php file


4. htmlentities($_POST['titulo']); - on php file


5. titulo: encodeURIComponent($("#titulo").val()) - on js file

And I've executed "service apache2 restart" each time done some alteration to .htacces, or used ini_set.

My PHP version is 5.5.3, to be more precise:

PHP 5.5.3-1ubuntu2.6 (cli) (built: Jul 7 2014 16:54:32) Copyright

Can someone help me?

Answer

Sorry guys.

The problem was the charset of my Codeignter and the database.

It was set utf-8, but, the database is latin1.
