So should XeTeX try to produce precomposed characters (normalized
form) from decomposed input where possible? Or is this a problem that
the font should be handling?

I'm curious because I use a lot of combining marks in my work, e.g. x̱
and ą́, some of which have precomposed characters standardized and
some of which do not. I was bit by this same problem once before, as
well.
