You're correct. But since this list is so long, and the probability to get
biblio records using the vast majority of those encodings is near zero,
the question is: which of those encodings do you need which is missing
in Koha?

It's hardcoded in admin/z3950servers.tt Koha page template. You can ask
for an enhancement on:

   http://bugs.koha-community.org

and propose a patch, or find someone proposing a patch for you.

Kind regards,
