There are also "Reiwa" related packages other than ICU.

* Mozc

Mozc should support conversion "reiwa" to "令和",
and common era to Reiwa era.

Debdiffs for disco/cosmic/bionic/xenial are already uploaded a week ago.

  https://bugs.launchpad.net/ubuntu/+source/mozc/+bug/1823444

Is current state waiting tob published to proposed pocket?

* LibreOffice

LibreOffice supports to display Reiwa era in 6.2.3 (eoan).
Will be disco/6.2.2 SRU'd to 6.2.3?

Debdiffs for bionic/6.0.7 and xenial/5.1.6 are already uploaded by
ikuya-san.

  https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1827451

And Reiwa patch now imported to upstream 6.1.x branch.
If 6.1.6 will be released, we can SRU for cosmic/6.1.5 too.

* Noto Sans CJK

Noto Sans CJK V2.001 is released to support Reiwa's ligature (U+32FF).

  https://github.com/googlefonts/noto-cjk/releases/tag/NotoSansV2.001

New upstream release bug is already filed in Debian.

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926753

Generating diff of font package is difficult, we should do SRU for stable
releases.
However fonts-noto-cjk package affects Chinese and Korean users,
if we do SRU, we needs to consult these users.

* OpenJDK

OpenJDK support Reiwa in 8u212-b02, 11.0.3+7, 12.0.1.

  xenial: 8u191-b12 / -
  bionic: 8u191-b12 / 11.0.2+9
  cosmic: 8u191-b12 / 11.0.2+9
  disco: 8u212-b01 / 11.0.3+7
  eoan: 8u212-b03 / 11.0.3+7

8u212 has security fix. Should be update xenial/bionic/cosmic too?

  https://bugs.launchpad.net/ubuntu/+source/openjdk-8/+bug/1826001

How about OpenJDK 11 should be updated?

* glibc

glibc already fixed several branches.

  https://sourceware.org/bugzilla/show_bug.cgi?id=22964

Ubuntu imports these fixes in disco and eoan only.

However I think this fix is not so important for older releases.

* ICU

Just for reference:

  https://bugzilla.redhat.com/show_bug.cgi?id=1677093

* unicode

Unicode 12.1 will be released in the nera future.

  https://unicode.org/versions/Unicode12.1.0/

This release just add "U+32FF SQUARE ERA NAME REIWA".

unicode package will affects this release.


* poppler-data

The Adobe-Japan1-6 Character Collection specification is updated to
Adobe-Japan1-7.

  https://blogs.adobe.com/CCJKType/2018/08/aj17-subset-fonts.html

poppler-data and other cmap file packages may need to update
for TeX and PDF viewer.

For example, following is poppler-data's ticket.
