[Bug] [Android] Response Header Encode

[diogodumas78]

Describe the bug
hey guys,
I am facing some problems with the plugin. I migrated from angular/common/http. Everything works perfectly. However, when I receive a business message in the response header, I was unable to receive it with the correct encode. The message comes with a code instead of words with an accent or ç. Has anyone experienced this and managed to resolve it?

thanks in advance
