The version of unicode-data in the proposed pocket of Xenial that was
purported to fix this bug report has been removed because one or more
bugs that were to be fixed by the upload have failed verification and
been in this state for more than 10 days.

** Changed in: unicode-data (Ubuntu Xenial)

  Support Japanese new era "令和 (Reiwa)"

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]

  Unicode data  include REIWA like it includes HEISEI. Reverse-build-
  depends need a rebuild to include the new data, followed by the
  following tests to make sure the data is taken into account.

  1) Rebuild reverse-depends of unicode-data; check that they build fine
  (ie. no regressions due to unicode-data changes):

  Reverse-Build-Depends
  =====================
  * console-data
  * courier-unicode
  * cyrus-imapd
  * fntsample
  * fonttools
  * gucharmap
  * ibus
  * julia
  * libxmlada
  * node-unicode-data
  * node-unicode-property-aliases
  * node-unicode-property-aliases-ecmascript
  * node-unicode-property-value-aliases
  * node-unicode-property-value-aliases-ecmascript
  * node-unicode-tr51
  * re2
  * safeclib
  * slang2
  * utf8proc
  * wcwidth
  * wine
  * wine-development

  
  2) Using gucharmap, verify that the SQUARE ERA NAME REIWA glyph point exists (there may not be a glyph associated as that is font-dependent.

  == 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. Use fonts-noto-cjk to display the
  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.
