+ * This test method makes use of {@link io.r2dbc.spi.R2dbcType#NCHAR} and + * {@link io.r2dbc.spi.R2dbcType#NVARCHAR} when binding Strings that contain + * non-ascii characters. By default, a String bind is mapped to the VARCHAR + * SQL type. This default mapping has the driver encode the value using the + * database character set. The database character set may not support + * non-ascii characters. Binding Strings with the NCHAR/NVARCHAR type + * configures the driver to encode the string using the national character set + * of the database. The national character set is either UTF16 or UTF8, and so + * it must support non-ascii characters. *
