A November 1983 specification proposed that domain names would have "only letters, digits and hyphen"--which meant that alphabets in Cyrillic, Arabic, Kanji, or Chinese sinographs could not be used in domains. Not even diacritical marks employed in German, French and Spanish were permitted. On Wednesday, delegates to a United Nations summit here complained that the ASCII-only choice was representative of an Internet culture that was far too English-centric and failed to respect other languages.
