mysql_real_escape_string(htmlspecialchars) function not working when editing values - php

Question

I'm using Italy language as main language in my website so when i edit details the some of language characters automatically converting to special character. does anyone know how to fix this issue...!
here is the code which i used to edit database value and convert specialchars
$title7 = mysql_real_escape_string(htmlspecialchars($_POST['title7']));
$description7 = mysql_real_escape_string(htmlspecialchars($_POST['description7']));
Here is the full code which i used to edit database values
// connect to the database
include('db.php');
if (isset($_POST['submit']))
{
// confirm that the 'id' value is a valid integer before getting the form data
if (is_numeric($_POST['id']))
{
// get form data, making sure it is valid
$id = $_POST['id'];
$language = mysql_real_escape_string($_POST['txtLanguage']);
$pkg_name = mysql_real_escape_string($_POST['pkg_name']);
$category = mysql_real_escape_string($_POST['category']);
$title = mysql_real_escape_string($_POST['title']);
$description1 = mysql_real_escape_string($_POST['description1']);
$title2 = mysql_real_escape_string($_POST['title2']);
$description2 = mysql_real_escape_string($_POST['description2']);
if ($pkg_name == '' || $category == '')
{
// generate error message
$error = 'ERROR: Please fill in Package name field!';
//error, display form
renderForm($id,$language,$pkg_name,$category,$title,$description1,$title2,$description2);
}
else
{
// save the data to the database
mysql_query("UPDATE saved_packages SET
language ='$language',
pkg_name ='$pkg_name',
category ='$category',
title ='$title',
description1 ='$description1',
title2 ='$title2',
description2 ='$description2',
WHERE id='$id'");
// once saved, redirect back to the view page
header("Location: adm_view_package.php");
}
}
else
{
// if the 'id' isn't valid, display an error
echo 'Error!';
}
And here is the result

Don't use htmlspecialchars when save data to database.
You should only do:
$title7 = mysql_real_escape_string($_POST['title7']);
$description7 = mysql_real_escape_string($_POST['description7']);
And when render the data get from database, use it:
echo htmlspecialchars($title7);
echo htmlspecialchars($description7);
