This is just not helpful. I know Unicode has "weird stuff" in it. If I didn't, this post would not do much to teach me about them. As for a whitelist, it sounds like an incredibly huge effort to write a good one. Telling me I should do it without commenting on whether anyone else has tried and succeeded or failed leaves me where I was before reading this post. I was already thinking "boy, Unicode has some weird stuff in it. Wonder what I should do about it?"
