And the winner is ....... (drum roll) ....... DAVID WINSEMIUS!!!
Thank you hugely David. You have completely solved my problem.
The last bit with format.hexmode() so as to get "00A3" rather than
just "a3" was actually unnecessary; I could've lived with "a3". But it
was a nice bit of polish.
How you manage to find the relevant functions in the bewildering (to me)
superabundance of functions is impressive as well as astonishing.
Thanks again.
cheers,
Rolf

If I have a character such as "£" stored in a object called "xxx", how can I obtain the
hex code representation of this character? In this case I know that the hex code is "\u00A3", but
if I didn't, how would I find out?
I would like a function "foo()" such that foo(xxx) would return, say, the string
"00A3".
Close:
as.hexmode(utf8ToInt("£"))
[1] "a3"
Looking at the help page again I realized that there was a `format.hexmode` to
deliver as requested:
format(as.hexmode(utf8ToInt("£")), width=4, upper=TRUE)
[1] "00A3"
