In order to generate these files, refer to
https://wiki.mozilla.org/I18n:Updating_Unicode_version
For those too lazy to go to the link (or if the link no longer works), we need the
following files from http://www.unicode.org/Public/9.0.0/ucd/:
- UnicodeData.txt
- Scripts.txt
- EastAsianWidth.txt
- BidiMirroring.txt
- HangulSyllableType.txt
- SpecialCasing.txt
- ReadMe.txt (to record version/date of the UCD)
- Unihan_Variants.txt (from Unihan.zip)
As well as Identifier*.txt from http://www.unicode.org/Public/security/9.0.0/,
which should be put in a "security" subdirectory under the UCD folder, and
http://www.unicode.org/Public/vertical/revision-15/VerticalOrientation-15.txt put
in a "vertical" subdirectory.
I suggest downloading all files with GetEmAll, just in case.
Change the perl command a bit, as the guide seems to be outdated:
perl ../tools/genUnicodePropertyData.pl /path/to/platform/gfx/harfbuzz/src/ /path/to/platform/intl/icu/source/common/unicode/ /path/to/UCD-directory/
