That depends on engine.
>From what I understand, XeTeX does normalize the input, so NFD should
work fine. But I'm only speaking from memory based on Jonathan's talk
at BachoTeX. I might be wrong. I'm not sure what LuaTeX does. If one
doesn't write the code, it might be that no normalization will ever
I can also easily imagine that our patterns don't work with NFD input
with Hyphenator.js. I'm not sure how patterns in Firefox or OpenOffice
deal with normalization. I never tested that.
But in my opinion engine *should* be capable of doing normalization.
Else you can easily end up with exponential problem. A patterns with 3
accented letters can easily result in 8 or even more duplicated
patterns to cover all possible combinations of composed-or-decomposed
Arthur had some plans to cover normalization in hyph-utf8, but I
already hate the idea of duplicated apostrophe, let alone all
duplications just for the sake of "stupid engines that don't
understand unicode" :).
