The uniset upstream has accepted my patches that eliminate the Unicode plane offsets from the output in '--32' mode. Remove the corresponding filter in update_unicode.sh. This also fixes the issue that the plane offsets were not removed from the second uniset call. Signed-off-by: Beat Bolli <dev+git@drbeat.li> Signed-off-by: Junio C Hamano <gitster@pobox.com> |

TL;DR: Run update_unicode.sh after the publication of a new Unicode standard and commit the resulting unicode_widths.h file. The long version ================ The Git source code ships the file unicode_widths.h which contains tables of zero and double width Unicode code points, respectively. These tables are generated using update_unicode.sh in this directory. update_unicode.sh itself uses a third-party tool, uniset, to query two Unicode data files for the interesting code points. On first run, update_unicode.sh clones uniset from Github and builds it. This requires a current-ish version of autoconf (2.69 works per December 2016). On each run, update_unicode.sh checks whether more recent Unicode data files are available from the Unicode consortium, and rebuilds the header unicode_widths.h with the new data. The new header can then be committed.
