Indeed, nor is it in ASCII. So it might at least have encouraged attention to be paid to character encoding issues a decade or so earlier!
Who cares about ASCII (American standard code for…) in a British product? This, of course, would use BS-4730 (BS = British Standards Institute.) it has £ where ASCII has #.
There's no # on mac British keyboards! You have to hit option-4 (did I get that right, don't have a keyboard in front if me) to e.g. comment ruby code...
It's ⎇-3, not 4. ⎇-4 is ¢.
I cannot see £ sign on my keyboard, so that would be slightly inconvenient. :)
