Insert rupee symbol instead of Rs in magento

We have previously posted the solution for INR symbol. But that was playing with code, finally we were able to solve that problem in easy way. Here it goes:

Step 1: Goto: lib/Zend/Locale/Data/root.xml
Make changes in root.xml
find <currency type=”INR”> replace next line with this <symbol>Rs. </symbol>

Step 2: Goto: http://cdn.webrupee.com/js  or click
save the page as rupee.js and save it inside /js folder of the root.

Step 3: Goto: \app\design\frontend\default\your-theme\layout edit page.xml
After this <block type=”page/html_head” name=”head” as=”head”>
add <action method=”addJs”><script>rupee.js</script></action>

Step 4 : Clear cache by deleting all the files and folder inside /var/cache folder. Clear cache from back-end as well.
