Yes. You will also need to prepare a mapping file, see below. See
the example of how we define, for example, coding-systems for
MS-Windows codepages:
(The mapping files are in etc/charsets; the :map attribute of the
charset names the mapping file to use.)
Which are generated from the admin/charsets files, which in turn
sometimes pulled in from glibc. So the easiest route is to add a
LISPM like charset mapping following glibc (and then also see if it
can be included there). And then do,
(define-charset 'lispm
"LISPM"
:short-name "LISPM"
:ascii-compatible-p nil
:code-space [0 255]
:map "LISPM")
(define-coding-system 'lispm
"Lisp Machine encoding"
:coding-type 'charset
:mnemonic ?L
:charset-list '(lispm))
So that sorts it out for the native one, but what should be done for
the Unix friendly mapping? LISPM-ASCII, and similar as above?
