What is the parameter for Enable High ASCII characters and Unicode for data sources configured for non-Latin characters?

[2Charlie]

Is the parameter for Enable High ASCII characters and Unicode for data sources configured for non-Latin characters in JDBC sendStringParametersAsUnicode=true or different?

[BKBK]

Yes, they stand for the same thing. If you check Enable High ASCII characters and Unicode for data sources configured for non-Latin characters, that is the same as appending sendStringParametersAsUnicode=true to the JDBC URL.
