Hello!

In my application I need to get the UCS code point of characters found
in buffer.  What is the recommended way to do that?

I noticed that there is an `encode-char' function, but it seems to be
restricted to a subset of characters and has a fairly strange API (it
accepts a general CCS argument which accepts only one value).

My application can handle `encode-char' returning nil for some
characters, but I'd like to know if it's considered a "stable" API,
i.e. whether it will be removed or replaced in a future version of
Emacs.
