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.

Going about things the wrong way!
Try this one:
set the useUnicode to true
set the unicodeText of fld "euro" to (NumToChar(8364))
8364 is the Decimal of Hex 20AC
works on the G4 Mac,
get (at least) a single character, instead of the 3 generated by the
previous script
on Ubuntu 8.04
BLAST!

Richmond,
except that you can resize the pngs and jpegs using rev itself and thus
had
a image that will always look good. Before setting the htmltext, you get
the
size of the text font being used and then simply resize your euro icon. If
you start with a big icon, and reduce it to the current font size, you'll
not loose quality and can cope with any font size!
resize can happen offscreen and thus be extremely fast for a single icon,
just create a copy of the original image offscreen and resize it, use its
ID
on the htmltext and you're good to go!
no one can stop a good hack!

The only problem I can see with that is if the end-user has the ability
to
resize fonts in the text-field; if the fonts are too big the Euro will
look
small and silly, if the fonts are too small the Euro png will overlap
adjacent chars.

Klaus,
want to do a cheap trick? create a little euro sign png or jpeg and use
the
imagesource of char something to put it inside a field, or use the
htmltext
with something like <img src="<id of image>" /> and there you'll have
your
EURO icon inside a field and no need to fiddle with fonts!
:D

Hi all,
any hint on how to handle crossplatform EURO signs?
I mean the euro sign is unfortunately NOT translated
isotomac/mactoiso, so how do you handle user input of this
(and other) character(s) in your crossplatform apps/stacks/databases?
Not to mention of ERUO signs in label fields, when you do not
want to loop over all fields and place the appropriate signs
on "pre-/openstack".
Any hints heavily appreciated, inm the meantime we use "EUR" ;-)
Best
Klaus
