here are the two lines of code in which I'm printing the special characters '>' and '>>'. however, they are being displayed as diamonds w question marks on the webpage.
paginationHtml = paginationHtml+\"<a href='javascript:void(0)' onclick='getCommentList(\"+next_page+\")'>Next› </a> \";
paginationHtml = paginationHtml+\"<a href='javascript:void(0)' onclick='getCommentList(\"+page_count+\")'>Last» </a> \";
The problem was I needed to change the encoding of my file. In PHPStorm, go to 'File' then 'File Encoding'. For me, I needed to choose 'UTF-8' encoding. I converted the code and now the ">>" characters show up fine in the website!
