Yes, but most font providers don't have such minority languages in mind.
(SIL would be an exception.)
That said, I've worked with such minority languages (including ones that
are just in the process of defining their writing systems), and I don't
recall a case where it was necessary to use a combining character
without a base character. Also, the original version of xetex was
developed by SIL (SIL also has some useful fonts), and SIL works with
such minority languages exclusively. So while it may be possible for
the *tex engine or fonts to omit the dotted circle, it doesn't seem to
be a very high priority.
That's of course not the same as saying it's never necessary, and the
OP's need to show it in tables is one valid (IMO) use case. If it can
be done with the method I mentioned, then that's probably good enough,
at least for that use case.
