There are many special HTML icons and characters that you can use in your websites for various purposes. Sometimes, instead of image files, I prefer using these characters or icons when applicable to make my websites and apps load faster or to make them look simpler. You can think of other useful/ practical usages for yourself.
Below you will find a link to a huge list of these characters/ icons along with their decimal codes and hex codes. When you want your webpage to render a special character/ icon in the list, just copy the decimal code and paste it into your page's HTML code.

Note: Please be patient, it may take some time to load the list. If it does not load the first time please try again.
Hope this helps someone.
