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 take place. 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 characters. 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" :).
