Bug Description

[Background]
Many packages are affected by the requirement to support the new era "Reiwa" (令和）

This is the meta bug to track packages that need fixes; which packages have already been SRUd to previous releases, how to prioritize the work needed, and general test cases for verifying that things are working as expected.

[Impact]
Users who run Ubuntu in Japanese.

[Test cases]

== Date output ==

1) Set date to 2019/05/01
2) Output date; verify that the year it is displayed as "令和元年"
3) Set date to 2019/04/30
4) Output date; verify that the year is diplayed as "平成31年"

=== Displaying formatted year for Japanese era with glibc ===

Run:
LC_ALL=ja_JP.utf8 date +%EY -d 20190430 # previous era (should still work as before SRUs)
or
LC_ALL=ja_JP.utf8 date +%EY -d 20190501 # new era (should now correctly display the new era)

[Regression potential]
This is a potentially large change as it impacts font display, character sets as well as date conversions. As such, extreme care should be taken to ensure that regressions are avoided, such that dates previous to May 1, 2019 continue to display as before, and dates onward are displayed with the new era symbols. The included test cases account for verifying the continued behavior or previous dates.

Hello Mathieu, or anyone else affected,

Accepted glibc into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/glibc/2.27-3ubuntu1.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

The verification of the Stable Release Update for glibc has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
