escape japaneese text in url

when the file names were actually in japaneese, IE by default will not converting the links from Japanese text to unicode URL format i.e %20. Here is the fix that required

Copy<a href="<%= product.product_image.url) %> ">SOME FILE NAME</a>
CHANGE TO :
<a href="<%= URI.escape(product.product_image.url) %>" >SOME FILE NAME</a>
