hexadecimal unicode input ?

hexadecimal unicode input ?

[Thomas Langen]

AFAIK the function insert-ucs-character allows only decimal numbers as 
argument for unicode characters. This is rather uncomfortable, as those 
characters are normally given as hexadecimal codes.

Is there a way to give the hex code as argument for any method to insert 
a unicode character?

Or does anybody know a better workaround than to convert manually from 
hex to dec?

Really?  Did you try to say #x1234, for example?

Thank you, that's the solution I was looking for - is it documented 
anywhere? (I had tried 0x1234, 1234h, and some other combinations I 
could imagine - they all didn't work.)

Maybe some extended help on the mule-ucs function "insert-ucs-character" 
would be useful.

This is not a feature of any specific function. It is a feature of the
Lisp reader. You can use hexadezimal, octal or binary notation
anywhere in Emacs Lisp code:

(print 4660)
(print #x1234)
(print #o11064)
(print #b1001000110100)

See the node "Integer Basics" in the ELisp manual.

BTW, does it make sense to install mule-ucs in Emacs-21.3 ?
Looks like most of its capabilities are there out of the box, while
mule-ucs was not updated since April 2001.

Shame on me, I had forgotten about that manual - thanks for your help 
(and to Oliver Scholz, too).
