To type special characters in Windows, hold the Alt key, type the number code associated with the special character you want using the numpad that's located on the right side of your keyboard. The row of numbers above your letter keys won't work.

Pressing the "Alt" key while typing a code on the number pad on Windows results in a special character. Press the "Opt" key on Mac to find special characters like the "Alt" key on Windows. On Linux and Chromebooks, you can press Ctrl + Shift + U to type any Unicode character, as long as the font you're typing it in supports it.
