Character Map / symbols - £$¥¢©How to type special characters or symbols in Windows
If you need to type special characters or symbols which you can't find on the keyboard, such as £, $, ¥, ©, ½, etc., then press Start and type Character Map. Then hit enter, or select character map from the list to open the Character Map.
From there you can find the special character or symbol you are looking for, choose a font if necessary, and learn the keystroke to type that character. You can double-click the character to select it, then copy it using the copy button and paste the character into the document or app you are using.
(Copy and Paste can also be achieved by pressing Cntrl + C and Cntrl + V.)
It's interesting to note that a few of these characters in Windows 10 are also available as emoji.
