   1TL;DR: Run update_unicode.sh after the publication of a new Unicode
   2standard and commit the resulting unicode-widths.h file.

   4The long version
   5================
   6
   7The Git source code ships the file unicode-widths.h which contains
   8tables of zero and double width Unicode code points, respectively.
   9These tables are generated using update_unicode.sh in this directory.
  10update_unicode.sh itself uses a third-party tool, uniset, to query two
  11Unicode data files for the interesting code points.
  12
  13On first run, update_unicode.sh clones uniset from Github and builds it.
  14This requires a current-ish version of autoconf (2.69 works per December
  152016).
  16
  17On each run, update_unicode.sh checks whether more recent Unicode data
  18files are available from the Unicode consortium, and rebuilds the header
  19unicode-widths.h with the new data. The new header can then be
  20committed.
