Bug ID: 2240458
Summary: Perl 5.38 breaks Irssi locale
Product: Fedora
Version: 39
Hardware: x86_64
URL: https://github.com/irssi/scripts.irssi.org/issues/857
OS: Linux
Status: NEW
Component: perl
Severity: medium
Assignee: jples...@redhat.com
Reporter: mjusz...@redhat.com

Target Milestone: ---
Classification: Fedora
After upgrade to Fedora 39 beta one of scripts in irssi (irc client) broke.
After checking what is going on (I do not know Perl) I found out that length of
string was reported with negative sign.
Opened a ticket at Irssi github account
https://github.com/irssi/scripts.irssi.org/issues/857 and went through
debugging a bit.
Turned out that Perl 5.38 drops locale settings when embedded in C. There is a
bug for it already: https://github.com/Perl/perl5/issues/21366
I do not know which solution should be taken to make it work properly. For
irssi script I have hacky workaround. But would be nice to not have such bug on
release of new Fedora version.
Reproducible: Always
Steps to Reproduce:
1. set locale to any UTF-8 one (I use pl_PL.UTF-8)
2. run irssi
3. run "/script exec print Text::CharWidth::mbswidth("─")" command
Actual Results:
Should return "1"
Expected Results:
Returns "-1"
irssi-1.4.4-5.fc39.x86_64
perl-5.38.0-500.fc39.x86_64
