quarkus: Broken encoding of data retrieved from MS SQL via reactive hibernate

Describe the bug

If data was put into a mssql database via direct sql query(e.g. by using vertx pool or file in quarkus.hibernate-orm.sql-load-script system property) and was retrieved via hibernate reactive session, then all non-ASCII symbols in it will be replaced by either corresponding ASCII symbols(“Č”->“C”) or with some garbage.

Expected behavior

Any data should be retrieved the same as it was put in the database

Actual behavior

Data gets corrupted

How to Reproduce?

Reproducer: https://github.com/fedinskiy/quarkus, branch reproducer/mssql-encoding How to run: mvn clean verify -pl io.quarkus:quarkus-integration-test-hibernate-reactive-mssql -Dtest-containers -Dstart-containers

File HibernateReactiveMsSQLTest contains several tests: vertxQuery — data is put to the database via MSSQLPool.query and retrieved via Mutiny.Session.find. Fails vertxRetrieval — data is put to and retrieved from the database via MSSQLPool.query. Fails persisted — data is put to the database via Mutiny.Session.persist and retrieved via Mutiny.Session.find. Succeeds imported — data is put to the database via quarkus.hibernate-orm.sql-load-script Quarkus property and retrieved via Mutiny.Session.find. Fails jdbc — data is put to the database via quarkus.hibernate-orm.sql-load-script Quarkus property and retrieved via jdbc. Succeeds sanity — send data over the network without accessing the DB
