On a PHP project, in which header is imported trough PHP, special characters such as "ñ" or "á" do not appear.
Database is correctly encoded as UTF8-general-ci, and these characters display correctly inside the database. The issue is that when showing them on the site, all special characters look like this (it shoul be Germán Álvarez):

Is this because of importing head trough PHP (as seen abobe), instead of placing it directly on each PHP file? How can I solve this?
Header import code:
......
<html>
<?php
    include("../modules/head.php");
?>    
<body>  
......
Code inside file modules/head.php:
<head>
    <meta charset="UTF-8" />
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
