Browse special HTML symbols and find their character codes in the categories above. Every character has a code available in the following format Ӓ. Some of them has a more human-friendly entity code available which is not so widely supported in older browsers. An entity format example: & (amersand).
As you can see on the attached image, the characters might not render the same in each browser.
