"Unicode - encoded as UTF-8 - just works. Yes, I'm sure there are some edge-cases. But if you can't properly store human names in their native language, you're opening yourself up to a lawsuit." Those edge cases are for a large part in human names. There are rare Chinese characters that are not in unicode, those are rare because they are only used in a few names. And one can question if a language like Chinese with a long tail of very rare characters is not effectively an open-ended set. Someone invented those characters in the past, so why won't that process continue? All of that is not really relevant to the legal question as judges tend to take into account what is reasonable in the current day and age, which according to this court is to support at least accents.
