If I have a character such as "£" stored in a object called "xxx", how can I obtain the

I would like a function "foo()" such that foo(xxx) would return, say, the string
"00A3".
Close:
as.hexmode(utf8ToInt("£"))
[1] "a3"
Nice one. I have seen that function before, but I didn't remember it
this time. One part of the documentation makes it harder to find: it
talks about "UTF-8 code points", rather than "Unicode code points".
UTF-8 is the way the Unicode code point is encoded into bytes.

I have googled and otherwise searched around and have come up with nothing that
seemed at all helpful to me. If I am missing something obvious, please point
me at it.
(I have found a table on the web, which contains the information that I need, but it is
only accessible "by eye" as far as I can discern.)
Supplementary question: Suppose I have the string "00A3" stored in
an object called "yyy".
intToUtf8(as.hexmode('00A3'))
[1] "£"
How do I put that string together with "\u"
so as to obtain "£"? I thought I could do
xxx <- paste("\u",yyy,sep="")
but R won't let me use "\u" "without hex digits". How can I get around this?
Thanks.
cheers,
Rolf Turner
