GroupWise client users have complete flexibility in the characters they use in composing messages. Accented characters used by various European languages and double-byte characters used by various Asian and Middle Eastern languages are all acceptable in the GroupWise client and can even be combined in the same message text.
As an administrator, the only limitation you need to be aware of is that double-byte Asian and Middle Eastern characters should not be used in directory names and filenames within your GroupWise system. This limitation is based on operating system capabilities. You should also not use double-byte characters in passwords. You are free to use double-byte characters in GroupWise usernames, domain names, post offices names, and so on.
