Nga,
CuteChat works with unicode.
The CuteChat configuration wizard will help you install the CuteChat to your remote server.
Basically it will install the CuteChat table, stored procedures on your SQL Server database and upload all the necessary files to the remote server through FTP.
Hope it helps.
Let me know if you have any further questions.
