  How do we handle with it for buster? (and stretch?)

  Please let me know if you've noticed more

   - unicode-data [2]

     (debian)$ LC_ALL=ja_JP.utf8 date +%EY -d 20190501
     (fedora)$ LC_ALL=ja_JP.utf8 date +%EY -d 20190501
[2] Unicode 12.1 contains "令和"

unicode-data in Buster is currently at 11.0.0; there being a major release upstream 12.0.0 just after Buster freeze.

I've uploaded 12.0.0 to unstable; 12.1 is not officially released yet. unicode-data itself is small and easy to validate, but the following packages will need to be rebuilt as they build-depend on unicode-data (and typically hard-code the tables internally):

I've uploaded unicode-data 12.1.0~pre1-1 to experimental.

This includes Unicode-data 12.0.0 updated with the Reiwa changes from 12.1.0 directory on Unicode-data; there is no official 12.1.0 release yet.

The way unicode-data is patched/built, the changed files are in the upstream tarball UCD.zip ( + allkeys.txt and depcomp.txt). So I've put a file debian/reiwa.patch in the debian dir to document the changes. Only the files changing for ReiWa are changing (from what I can tell, the only changes in the other files in the upstream are version numbers/dates in comment lines on other other files).

Please test if this is suitable for Buster.

Best regards

Commander Vimes didn’t like the phrase “The innocent have nothing to fear,”
 believing the innocent had everything to fear, mostly from the guilty but in the longer term
 even more from those who say things like “The innocent have nothing to fear.”
