I think I will just stick with "und". And I will let the free text declare the regional assertion.

I think we'd probably just use the three-letter ISO-639-2 code "und" 
('undetermined'), but that of course fails to capture the "African"
part of the description. The ISO-3166 region designations can
be used to further specify, but I do not think that they include
continents (or anything bigger than countries), so you might
have to make up a private-use qualification to "und-". I've not
done that, so I  am speaking in ignorance, as always.
