how to show the foreign characters in tpl.php file
Make sure that your theme is using the utf-8 character set.  You can see this in the headers of the page:

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


You'll also want to make sure that the web server you are using to serve the page is sending the correct HTTP header as the response (you can use the web developer inspector tool in either Firefox or Chrome to see this).  It should be:

Content Type: "text/html; charset=utf-8"


If your browser is set to use a different content-type encoding this might also explain the difference.
