How to find and use special characters on your mac

So you want to use special characters from any specific font but do not have any idea how to do so? I had a look around and Google but did not find an appropriate answer so I tried myself and here is how I copied the Font Awesome and used it into my favorite Photoshop app.

Step 1: Hit command + space to open the spotlight.

Step 2: Type Font Book and you will see it into results, just select it and open.

Step 3: Select Font Awesome from the list and you will be able to see all special character.

Step 4: Select an icon you want and copy it using command + c. That is it, now you can past icon using Photoshop text tool.

Hope this help.
