David Handermann commented on NIFI-8612:
----------------------------------------
[~langheld] Thanks for reporting this issue. I tested UnpackContext on 1.13.2
with the testzip.zip file provided and confirmed the same problem. This issue
appears to be related to character set handling in Zip4j prior to version
2.7.0. NIFI-8313 included updating Zip4j to version 2.7.0 and testing
UnpackContent on the current main branch worked as expected. With that
verification, this issue will be resolved in the next release.
