How i can define chatset for serialization in Quarkus?

Question

I'm trying send to other system through RESTCLIENT data that is in the ISO-8859-1 encode but i'm have a error: "com.fasterxml.jackson.databind.JsonMappingException: Invalid UTF-8 middle byte 0xe3".

I would like change the serialization encode to ISO-8859-1 instead UTF-8, is possible?

If i convert to UTF-8 before send, it work, but i dont want this option bacause the database is ISO-8859-1.

I tried set -Dfile.encoding=ISO-8859-1 in JVM, the value is changed but the error persist.

JSON should be encoced in UTF-8, UTF-16 or UTF-32, see https://www.rfc-editor.org/rfc/rfc7159#section-8.1

Jackson automatically detects which UTF variant it should support. As explained in this SO answer, you can override this mechanism by providing a JsonGenerator to the ObjectMapper : Jackson ObjectMapper with UTF-8 encoding?

In Quarkus, you can customize the ObjectMapper via an ObjectMapperCustomizer as described here: https://quarkus.io/guides/rest-json#jackson

That being said, my advise it really to use UTF-8 (or UTF-16/UTF-32 if you need enhanced charsets) as it's standard in web services.

Thank you for your explanation, i didn't know about this information. We have databases with charset UTF-8 and ISO-8859-1 (legacy) but with this information we will research a migration plan. I managed to serialize with JSONB instead Jackson. – Emerson May 20 '20 at 13:50

I managed to serialize by changing to JSONB (Eclipse Yasson implementation) and added charset to media type header.

Setting a header does not change character encoding: the header is just a hint for the client receiving such message. If you really want to send JSON messages encoded in ISO-8859-1, you probably need to do it with a Filter which rewrites the responses from the system default encoding scheme (or the one configured at JVM level) to the desired one, ISO-8859-1. – giulianopz May 19 '22 at 21:13
