So we somehow have a charset that is not in charset_table, is that
what you are saying?  Because otherwise how could its ID be beyond the
table, when define-charset-internal enlarges the table as needed?

Any idea what charset is that, and where it is added/loaded?

FWIW, on my system, charset_table_used is 179, so maybe the mac port
defines some additional charsets?

Thanks.
