In my .html document where the form is i have
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
in the .php file where i connect to the database i tried with
mysql_set_charset('utf8');   
// and 
// <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
and this:
header('Content-Type: text/html; charset=utf-8'); 
The database rows are with Collation: utf8_unicode_ci and charset utf8
So my issue is that when i send the code from the html form through the php i see this in my database: ИзбереÑ
Here's the .php document code: 
    <?php
// header('Content-Type: text/html; charset=utf-8');
header('Content-Type: text/html; charset=utf8');
// mysql_set_charset('utf8_unicode_ci');  
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "dbname";
$name = $_POST['name'];
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// mysql_set_charset('utf8');
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 
$sql = "INSERT INTO oglasi (Name)
VALUES ('$name')";
if ($conn->query($sql) === TRUE) {
    echo "";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}   
$conn->close();
// mysql_set_charset('utf8');
?>
