Public bug reported:
[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]
Unicode data embedded into icu should include REIWA like it includes
HEISEI.
== Date conversion ==
On applications that support writing dates in long form, or with symbols
to denote era (either in X00.00.00 format or in GG1G5G1G format (G-
glyph; X- character):
1) Enable date formatting in each of the above formats that are supported (long
form or symbols)
2) Type in '2019/05/01' to be formatted, verify that it shows as "令和1年5月1日" or
"R1.05.01"
3) Type in '2019/04/30' to be formatted, verify that it shows as "平成31年4月30日"
or "H31.4.30"
== Character maps / font support ==
1) Search for character "SQUARE ERA NAME"
2) Verify that the results include at least "SQUARE ERA NAME HEISEI" and
"SQUARE ERA NAME REIWA" (there should also be Syouwa, Taisyou and Meizi), and
that the glyphs are readable:
- SQUARE ERA NAME HEISEI: ㍻
- SQUARE ERA NAME REIWA: 令和 (in a single glyph)
Display of the Reiwa square glyph is font-specific; it may show simply
as a empty square or a square with hex characters. If that is the case,
the unicode data supports the new character, but the selected font does
not include the new glyph.
[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.
