Codepage for Japanese text (other user with SlskNS client)?

To give some subtle criticism, the codepage selection is really "a bit" of the messy kind currently.

However, whether messy or not: the essential codepage of Japanese, Shift-JIS, is no longer selectable. I'm pretty sure it was available in a couple of the older builds. I went through all the codepages top-down and in reverse order, but nothing.

There is also an alt codepage that can be used in Windows I know of, and this is CP 932. But this one is nowhere to find.
