To my understanding, UCS-2 and UCS-4 are the names of Character Encoding Form (CEF), not Character Encoding Scheme (CES), and as CEF doesn't include byte serialization mechanism, it can't be a coding system. Only CES (UTF-XXX) can be a coding system. But, I don't know the definition of UCS-2BE. Is it just a limited UTF-16BE (limited to BMP)? Where is it defined officially? --- Kenichi Handa handa@m17n.org
