This page contains a list of HTML special characters. In HTML, special characters are typically those that can't be easily typed into a keyboard or may cause display issues if typed or pasted into a web page.

If you plan to use any of the special characters on this page, you should use either the HTML entity name or the HTML entity number. This will ensure that it displays correctly in most/all browsers.

For example, if you want to display a copyright symbol "©", you should use either © or © in your code.

HTML Reserved Characters

The following special characters are reserved in HTML. That is because these are the characters that make up the HTML language. If you use one of these characters in an article, the browser will try to interpret it as HTML. Therefore, you should use the entity name or entity number when you want to output any of these reserved characters.
