-------------------------------------

             Summary: Calcite supports Chinese issues
                 Key: CALCITE-3843
                 URL: https://issues.apache.org/jira/browse/CALCITE-3843
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.21.0
         Environment: First set environment variables:

System.setProperty("calcite.default.charset", "UTF-16LE");
System.setProperty("calcite.default.nationalcharset", "UTF-16LE");
System.setProperty("calcite.default.collation.name", "UTF-16LE$zh_CN");

When executing the statement of  select * from "T_P_BoM" where "RequiredPartNo"='中' , the following error occurred : While executing SQL [SELECT * FROM "T_P_BoM" WHERE "RequiredPartNo" = u&'\4e2d'] on JDBC sub-schema.

 

I think there is an error in the judgment here, which caused the subsequent process to enter quoteStringLiteralUnicode.
