Right, I want to call the LispCharacter constructor. CODE-CHAR yields
a java.lang.Character, as reported by (java:jcall "getClass"
(code-char #xnnnn)), so that's not quite enough.

To back up a little, what I really want is for ABCL to recognize
Unicode characters by name, e.g. #\BOX_DRAWINGS_LIGHT_VERTICAL and so
on. Towards that end, I believe, perhaps unreasonably, that if I can
wedge a new item into LispCharacter.lispChars, then I can call
LispCharacter.setCharName, and then -- presto, perhaps -- the reader
will recognize #\MY_NEW_NAME.

Then, of course, I'll be able to compile some new code which makes use
of those named characters without modifying that code. Some other Lisp
implementations recognize those out of the box; at least one needs to
have them defined, for which there is an internal Lisp function to do
it. It appears it's also possible with ABCL with a little more effort.

Thanks for your help, and all the best.
