Introduction
Following is the table containing entities or characters used for referencing in HTML, XSLT, and XML as a complete reference. In HTML, you can use specific code references to display special characters. As example is used to place a space in your text, in other words, a non-breaking space; and © is the equivalent of placing a copyright sign on the page, i.e., ©
However, in XSLT you are not allowed to use these types of characters, you need to use the ISO-8859-1 character set. So, instead of inserting as a non breaking space, you'd insert   and instead of © you'd use ©
