I thought about missing African letters like barred-R, barred-W, etc... with combining overlay "diacritics" (whose usage has been strongly discouraged within Unicode).
May be a font could handle theses combinations gracefully with custom glyph substitution rules similar to the automatic detection of ligatures. But may be they should not if Unicode will, in fine encode these characters separately without any canonical equivalence with the composed sequence.
Having spent weeks time researching African orthographies a few years ago, I'm inclined to think that such barred letters should be separately encoded: they constitute new Latin letters, not combinations of elements within orthographies such as base letters and combining marks. A problem, however, is that many such forms are found in unstable orthographies, and are difficult to document adequately for inclusion in proposals.
