Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Cause: Previously Unzip used function "fnprintf* for secure printing of string, which masked all unprintable ascii characters by '?'. In other words. wide characters weren't supported.
Consequence: Wide characters in filenames were evaluated as unprintable or "not safe for print" so were masked by '?'.
Fix: Modify the function according to upstream solution to support non-ascii encoding.
Result: Filenames with non-unicode encodings are printed correctly.
Unzip don't print right non-ascii filenames on stdout when you try print list of filenames inside archives and used -O/-I paramter with right encoding.
Reproducer:
1. create archive with non-ascii filenames (e.g. encoding CP866) - you can use this archive [0]
2. $ unzip -l -O 866 123.zip
Actual results:
Archive: 123.zip
