> The following test in JdbcTest throws "Cannot apply = to the two different
> charsets ISO-8859-1 and GBK"
> {code:java}
> CalciteAssert.hr()
> .query("select \"name\", \"empid\" from \"hr\".\"emps\"\n"
> + "where convert('a' using GBK)=_GBK'a' order by \"empid\"")
> .returns("name=Eric; empid=200\n"
> + "name=Sebastian; empid=150\n"
> + "name=Theodore; empid=110\n"
> + "name=Bill; empid=100\n");
> {code}
> Since we try to convert 'a' with GBK, the charset of its result should also
> be treated as GBK.
