I am looking for a resource that illustrates and comprehensively describes the unicodes for modern Gaelic. It would also be cool if there were samples of the standard glyphs, diacritics, and most common alternates. Also very cool would be charts or diagrams to break these up into Irish, Welsh, and Scottish Gaelic. Evidently, there are some differences. The information I've been able to gather covers more archaic versions with no real concern for typography or type design.

Thanks,
James
