The server to which the Open Client and Open Server is connecting must support 2-byte Unicode datatypes, and use UTF-8 as the default character set.
If the server does not support 2-byte Unicode datatypes, the
server returns an error message: “Type
not found. Unichar/univarchar is not supported.”
CS_UNICHAR does not support the conversion from UTF-8 to UTF-16 byte format for CS_BOUNDARY and CS_SENSITIVITY. All other datatype formats are convertible.
CS_UNICHAR does not provide C programming operations on UTF-16 encoded Unicode data such as Unicode character strings.
