You need to complete the following step to change page encoding:
Add this line somewhere below HEAD tag:
<meta http-equiv="Content-Type" content="text/
Note: You can change UTF-8 to any other encoding you want, but we recommend using UTF-8.
If this does not help, please check if your files are really encoded in UTF-8. You can do this with software such as Notepad++.
You may also try to add this line at the top of your index.php page:
header('Content-Type: text/html; charset=utf-8');
