I never really understood the insistence on diacritics. My name is properly written in Hebrew characters, and contains sounds not present in the English language. Many more people use CJK, Cyrillic, Arabic, or other characters. The writing system in use by many people and companies for the English language does not support any of these characters, and nor does it support diacritics. Some variants (in particular, see airlines) use only capital letters, with no spaces or dashes; this also seems reasonable to me (even when my name is somewhat mangled as a result). So just like a CJK/Cyrillic/Semitic name has to be roughly transliterated into Latin characters, and inevitably pronounced differently than in its origin language, why shouldn't the same be true for names with diacritics? Saying that the One True International Alphabet is latin-1 or whatever is rather arbitrary. And no, the solution isn't to give up on cross-cultural communication, nor to require that every human learn all the characters in Unicode.
