Encoding aStringinto UTF-8 isn't difficult, but it's not that intuitive. This article presents three ways of doing it, using either core Java or Apache Commons Codec. As always, the code samples can be foundover on GitHub. Get started with Spring 5 and Spring Boot 2, through theLearn ...

The DBAs had set up rules so that by looking up the language code for a record, you could determine what encoding to use for the content (which was stored in the DB as raw bytes). I think you need to talk to the DBA for this database and have them explain how encoding is ...
