The homoglyph data would be a useful starting point for the feature
I imagine, indeed.  But from the message that started this thread, "K"
is a homoglyph, yet highlighting it everywhere doesn't sound like a good
idea, so basically we need to associate with each homoglyph char
a context where it is expected and only highlight it when it appears in
a different context (or maybe rather when it appears in the context of
its peer).
