Description Miroslav Suchý 2011-03-09 09:57:01 UTC 
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
Comment 2 Roman Rakus 2011-04-18 12:09:22 UTC 
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)
Comment 3 RHEL Program Management 2011-07-06 01:33:07 UTC 
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.
Comment 4 Roman Rakus 2012-05-09 10:51:35 UTC 
Miroslav you can use some command in PS1 to decode Pune. Does it satisfy your need?
Comment 6 Miroslav Suchý 2012-08-23 13:31:41 UTC 
Still reproducible on RHEL6.3 with bash-4.1.2-9.el6_2.x86_64
Comment 7 Roman Rakus 2013-05-16 19:35:14 UTC 
Upstream didn't responded. Adding another library dependency isn't necessary weight and there is easy workaround.
Comment 8 Miroslav Suchý 2013-05-17 07:30:57 UTC 
I do not see it discussed in upstream. But anyway - I will file this in upstream.
