No, \XeTeXinputnormalization is not what I am looking for. In my
example, Greek language, alpha and combining acute are there just for
the sake of simplicity. In the real material, I have more complex
pairs that certainly do not have precomposed variants.

To put it the other way, I need a simple way to tell xetex not to
hyphenate before such and such characters, in this particular case,
before U+0301, U+0302, U+0303, etc. (Whatever harm it does to the
actual language of the text in question.)
