> Hi, 
> I am using a calcite-core.jar version 1.28. I am facing an issue with a sql query targeted for Oracle database (12.1.0.2.0). Example query is:
> *select * from sample where column1 in ('héb', 'sio', 'dép');*  
> Query transformed and executed by Calcite:
>  *select * from sample where column1 in (u&'h\00e9b', 'sio', u&'d\00e9p')* 
> which gives sql error as: ORA-00907: missing right parenthesis. 
> I tried providing a system property calcite.default.charset=UTF-8 but it didn't help. I tried to debug the code and found that method [https://github.com/apache/calcite/blob/1d4f1b394bfdba03c5538017e12ab2431b137ca9/core/src/main/java/org/apache/calcite/sql/SqlDialect.java#L575] is causing this encoding which gets invoked from [https://github.com/apache/calcite/blob/1d4f1b394bfdba03c5538017e12ab2431b137ca9/core/src/main/java/org/apache/calcite/sql/SqlDialect.java#L425] . 
> In the older version of calcite-core 1.15, the same query used to work. I have no idea since which version of calcite-core, it started failing.
