The sever to which the Open Client/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. For full support for Unicode character strings, you must use the Sybase product, Unilab. See the Unilib Reference Manual at The reference manual is part of the Sybase Unicode Developers Kit 2.0.
