Replacement for CJK's \Unicode macro

Question

I need a replacement for the \Unicode macro from CJK. It takes two decimal numbers as arguments and inserts #1*256 + #2 into the token stream (or something like that; it's a way to write Unicode characters by code like A in XML).

That should be possible with a tiny bit of lua code. Any pointers?

Answer 1

As far as I can tell, a definition such as

\newcommand{\Unicode}[2]{\char\numexpr#1*256+#2\relax}

should be what you need.
