ExpressConnect for HANA DB converts character sets depending the default values for the Replication Server rs_charset, unicode_format, and dsi_charset_convert parameters.
If rs_charset is set to iso_1, unicode_format is set to string, and dsi_charset_convert is set to on, ExpressConnect for HANA DB passes all data in its native form with no conversion. Unicode literals are not supported.
If rs_charset is set to any supported character set, unicode_format is set to string (the default), and dsi_charset_convert is set to on, ExpressConnect for HANA DB converts all SQL language and character parameter data to UTF-16.
