Why isn't my Turkish currency symbol showing on my site?

Since March, 2012 the Turkish lira symbol changed from "TL" to Turkish lira symbol 8x10px.png.  Some computers do not have the correct font yet and cannot see it as it should be.  Instead they will see an empty box where the symbol should appear.  To solve this problem, you can add the following script in the head section of your sites using Turkish currency.  To do this go to Sites > [Site Name] > Settings > SEO/HTML tab. Click on "Edit HTML Head Content" to expand this section.  Paste this script into this area:

<link rel=stylesheet href= "http://fonts.googleapis.com/css?family=Source+Sans+Pro:400,700,400italic,700italic&amp;subset=latin,latin-ext">

<style> body { font-family: Source Sans Pro; } </style>
