[Bug]: [REST Client] Character encoding issue responses in Hop 2.15 e 2.14 #5805

@ClaudioCurzi

Description

@ClaudioCurzi

Apache Hop version?

2.15.0 e 2.14.0

Java version?

openjdk17 e openjdk21

Operating system

Windows

What happened?

The REST Client transform in Apache Hop 2.15 (and 2.14) does not correctly handle UTF-8 encoded responses from REST APIs.

Characters are garbled/corrupted in the output, even though the server response is correct (also I have tried in Pentaho 9, with Java8, and the response is parsed correctly).

Steps to Reproduce

  1. Create a pipeline with a REST Client transform
  2. Call a REST endpoint that returns UTF-8 encoded JSON (e.g., {"result":{"code":0,"desc":"OK"}})
  3. The response contains non-ASCII characters that appear corrupted
  4. Server logs confirm the response is correctly encoded in UTF-8
