Oracle SQL file ( UTF-8 ) Into StreamCommand not returning correct character set

[#1]

Using the ExecuteStreamCommand processor, I am trying to execute a SQL file which has multibyte characters included in the file.

Sample SQL command :

select 'Lávañya' from dual;

The expected output should be the exact same characters. When running the file directly with the sqlcl client via command line , the output works as expected. However, when processed through the ExecuteStreamCommand processor the output results:

Lávañya

I have set nifi to use the UTF8 encoding:

java.arg.8=-Dfile.encoding=UTF8

I have tried setting the encoding directly into the sql file, and this doesn't change the output.

Running Windows Server 2019

NiFi 1.14.0

Thanks in advance, any help is appreciated.
