Suggestion:

replace in ZipHelper return new ZipArchiveInputStream(is, StandardCharsets.UTF_8.toString(), true, true); with return new ZipArchiveInputStream(is, StandardCharsets.UTF_8.name(), true, true);

Nice catch! Thank you! Do you have some simplified test document to reproduce the issue? Most welcome would be a patch of yours where there is a test involved that earlier fails and with your patch would be working! Thanks in advance!
