Unicode 5.0 corresponds to ISO 10646:2003, including amendments 1–3. Unicodes since 2.0 are backwards-compatible -- no characters are removed or replaced in new versions, only added. ISO 14651 defines string sorting order. RFC 3629 defines UTF-8, an [[ASCII]]-compatible Unicode encoding, usable in any context designed for [[ASCII]] but insensitive to characters' meanings.
