When importing JUnit results via Jenkins, the test summary and definition is being displayed incorrectly

Description
When using a Post-build Action in Jenkins to import JUnit results, the tests summary and definition created in Jira does not show as in the XML file.
This does not happen when we import directly via Jira UI or REST API.

Attached the results XML file used. results.xml

Pre-conditions

• Have a Jenkins project;
• Have a "Xray: Results Import Task" with the following configuration (changing the file path and project Key accordingly):
  

How to reproduce

1. Go to a project in Jenkins where we have Xray: Results Import Task configured
2. Click "Build Now" on the left menu
3. See the tests in Jira
   

Actual result/Attachments
The tests appear with characters different from what is passed in the results XML

Expected result
The test summary and definition look equal to the XML file.
