Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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.

Description of problem:
I have machine which has non latin domain name in hostname and my $PS1 include \h and the hostname is displayed in Pune encoding instead of proper Unicode.

[root@xn--luouk-k-z2a6lsyxjlexh ~]# hostname
xn--luouk-k-z2a6lsyxjlexh.lab.FILTERED
[root@xn--luouk-k-z2a6lsyxjlexh ~]# host xn--luouk-k-z2a6lsyxjlexh.lab.FILTERED
žluťoučký-kůň.lab.XXX has address 10.34.XX.XX
[root@xn--luouk-k-z2a6lsyxjlexh ~]# echo $PS1
[\u@\h \W]\$

Version-Release number of selected component (if applicable):
# rpm -q bash
bash-4.1.2-3.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. created DNS record for machine with non latin character
2. set PS1=\h

  
Actual results:
hostname is in Pune encoding:
xn--luouk-k-z2a6lsyxjlexh

Expected results:
I expect it decoded from Pune to Unicode
žluťoučký-kůň

People can use some external script/command to decode Pune.
Direct inclusion in bash seems to be not possible (so far no answer from upstream)

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.

Miroslav you can use some command in PS1 to decode Pune. Does it satisfy your need?

Still reproducible on RHEL6.3 with bash-4.1.2-9.el6_2.x86_64

Upstream didn't responded. Adding another library dependency isn't necessary weight and there is easy workaround.

I do not see it discussed in upstream. But anyway - I will file this in upstream.
