Argh. My books on typography don't refer to "antique s". But I think, since
you mention African, there might be a coding answer to your question. Let's
see what you say....

Um, don't you mean only the 'antique s' has a descender in plain serifed

Now I am confused because I thought you were talking about something else.
Maybe it is just a question of terminology.

The location isn't so important. And there are other African characters
which are elsewhere (the IPA block for instance).

0053 LATIN CAPITAL LETTER S
0073 LATIN SMALL LETTER S
017F LATIN SMALL LETTER LONG S
The laft character here is the one that looks juft like a fmall letter f
without the crofs bar. In italics it does, juft as the f does, take a long
1E60 LATIN CAPITAL LETTER S WITH DOT ABOVE
1E61 LATIN SMALL LETTER S WITH DOT ABOVE
1E9B LATIN SMALL LETTER LONG S WITH DOT ABOVE
These, for your interest, are used in Irish Gaelic when written in the
Gaelic script. (One reasion I take such an interest in your question.)
01A9 LATIN CAPITAL LETTER ESH
0283 LATIN SMALL LETTER ESH
The capital letter looks like a GREEK CAPITAL LETTER SIGMA. The small
letter looks like a vertical version of an italic letter f with long
descender, or a long s fused to a j, however you prefer to envision it.
Is this an answer to your question?
