Is there a function to get the character at point? I see get-byte,
which would work for an ASCII coded file, but I believe Emacs has some
support for multi-byte character sets.

If you type C-h f char TAB, you will see a bunch of functions whose
names begin with "char". Then you might wildly guess that the first hit,
char-after, is what you are looking for, and if you actually select
that, the wild guess is confirmed.

Thanks! I believe I did look at the char* functions. If it had been
named char-at I would have gotten it. It should be noted that the help
for "char-after" says
--------------------------------------------------------------------------------
(char-after &optional POS)
Return character in current buffer at position POS.
POS is an integer or a marker and defaults to point.
If POS is out of range, the value is nil.
----------------------------------------------------------------------------
The concept of "point" being between characters, was unfortunately
followed in naming the function, and then luckily ignored in the help
for the function.

General functions are generally easier to find in the elisp manual.

File: elisp, Node: Top, Next: Introduction, Prev: (dir), Up: (dir)
Emacs Lisp
**********
...
* Text:: Examining and changing text in buffers.
...

-> (info "(elisp) Text")
And the first function of the first entry is what you were looking for.

OK, thanks, I will check that in the future.
