Sybase does not differentiate between multibyte and wide character strings while inserting or retrieving data from the server. During input binding, RWWString data are converted to RWDBMBString data before binding. In output binding, the data is received as an MBString and then converted to a WString, if required.

RWWStrings should not be used for binding with Sybase datatypes unichar or univarchar. Even if they contain UTF-16 encoded data, RWWString data is converted to RWDBMBString before binding and hence will no longer bind UTF-16 encoded data.
