They may have removed it from printout on new keyboards but they didn't remove it form the United Kingdom keyboard layout in Windows! And definitely won't remove from ALL UK keyboards - especially not from the one I'm using here
Have you even tried to use the RightAlt + 0128 with top number keys?
When you search for the instruction on that on Microsoft pages you will find the following:
Inserting ASCII characters
To insert an ASCII character, press and hold down ALT while typing the character code. For example, to insert the degree (º) symbol, press and hold down ALT while typing 0176 on the numeric keypad.
You must use the numeric keypad to type the numbers, and not the keyboard. Make sure that the NUM LOCK key is on if your keyboard requires it to type numbers on the numeric keypad.
So no luck on most laptops ;( unless we could disable that useless internal shortcut.
