ZheHu commented on CALCITE-6730:
--------------------------------
My mistake. We should encode string with the default source charset at runtime
instead of translating charset in earlier stage.
BTW, the PR is ready for review. Appreciate any comments.

> Key: CALCITE-6730
> URL: https://issues.apache.org/jira/browse/CALCITE-6730
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.38.0
> Reporter: ZheHu
> Assignee: ZheHu
> Priority: Major
> Labels: pull-request-available
>
> Unlike standard CONVERT function implemented in Calcite:
> {code:java}
> convert(string bytea, src_encoding name, dest_encoding name)
> {code}
> Oracle's [CONVERT
> |https://docs.oracle.com/en/database/oracle/oracle-database/19/nlspg/sql-and-plsql-programming-in-global-environment.html#GUID-7E4AA2C5-8CD7-4836-AA69-6C8E02594FAC]
> works like:
> {code:java}
> convert(string bytea, dest_encoding name[, src_encoding name])
> {code}
> If the 'src_encoding' parameter is not specified, then it uses the default
> character set.
