Crossplatform EURO sign?

[Richmond Mathewson]

Slightly parenthetically, but,

about 34 years ago a wonderful Maths teacher, one "Bonehead" Barker,
taught me how to count, add, subtract, divide and multiply in hex;

needless to say, I cannot remember anything of it; more's the pity.

However, I did discover that the Calculator.app on Mac  can 'flip' from
the boring, vanilla, pocket calculator simulcrum into something
altogether a lot more sexy: Command-3 gives you a 'scientific
calculator' (never could quite understand what the 'sciemtific'
meant in that context); and, Yippee-Doo, a way to go back and forth
between Decimal and Hex numbers (and Octal and Binary, if you are
having a really heavy day), and, wonder-of-wonders, it will,
magically reveal which unicode character that Hex number is linked to.

And, while I'm on a roll, I am currently 'pushing' my tinies, in my school,
through some relatively punishing exams; and having lots of sadistic fun
by making them work out their own percentage results with a slide-rule.

Depressingly enough, they all enjoy using slide-rules and have started 
asking
me where they can buy them. . . . .

------------------------------------------------

I suppose it could be quite fun to run up a Revolution stack to convert
between Hex and Decimal.
