You can type the EURO € sign / symbol on almost any PC keyboard by pressing Left ALT+0128 (type the numbers on the numeric keypad while holding down the Left ALT button).
On a laptop computer without a numeric keypad you need to hold Left ALT+Fn+0128
If you still cannot get it to work then select it with your mouse from here € then right-click with your mouse then select copy and paste it where you need it.
Please note that not all fonts have the EURO € symbol !
