- same as for the early Unicode Tools setup and data refresh:
https://github.com/unicode-org/unicodetools/blob/main/docs/index.md
https://github.com/unicode-org/unicodetools/blob/main/docs/inputdata.md
- mkdir -p $UNICODE_DATA
- download Unicode files into $UNICODE_DATA
+ new since Unicode 15.1:
for the pre-release (alpha, beta) data files,
download all of https://www.unicode.org/Public/draft/
(you can omit or discard the UCD/charts/ and UCD/ucdxml/ files/folders)
+ if one of us produces the alpha.zip or beta.zip collection of data files for publication,
then we can use its contents directly (no FTP from unicode.org necessary)
+ for final-release data files, the source of truth are the files in
https://www.unicode.org/Public/(version) [=UCD],
https://www.unicode.org/Public/UCA/(version),
https://www.unicode.org/Public/idna/(version),
etc.
+ use an FTP client; anonymous FTP from www.unicode.org at /Public/draft etc.
+ subfolders: emoji, idna, security, ucd, uca
+ whichever way you download the files:
~ inside ucd: extract Unihan.zip to "here" (.../UCD/ucd/Unihan/*.txt), delete Unihan.zip
~ split Unihan into single-property files
~/unitools/mine/src$ py/splitunihan.py $UNICODE_DATA/UCD/ucd/Unihan
~ TODO: for updating ICU, we should not need Unihan.zip contents, correct?
+ alternate way of fetching files, if available:
copy the files from a Unicode Tools workspace that is up to date with
https://github.com/unicode-org/unicodetools
and which might at this point be *ahead* of "Public"
~ before the Unicode release copy files from "dev" subfolders, for example
https://github.com/unicode-org/unicodetools/tree/main/unicodetools/data/ucd/dev
- get the CLDR version of GraphemeBreakTest.txt from CLDR (if it has been updated there already)
or from the UCD/cldr/ output folder of the Unicode Tools:
From Unicode 12/CLDR 35/ICU 64 to Unicode 15.0/CLDR 43/ICU 73,
CLDR used modified grapheme break rules.
This might happen again.

unicodetools issue #492
- cp -v $UNICODE_DATA/security/confusables.txt $ICU4C_UNIDATA
+ TODO: modify preparseucd.py to copy this file
* Note: Since Unicode 15.1, data files are no longer published with version suffixes
even during the alpha or beta.
Thus we no longer need steps & tools to remove those suffixes.
(remove this note next time)
* process and/or copy files
- cd $ICU_SRC/tools/unicode
py/preparseucd.py $UNICODE_DATA $ICU_SRC
+ This writes files (especially ppucd.txt) to the ICU4C unidata and testdata subfolders.

* update spoof checker UnicodeSet initializers:
inclusionPat & recommendedPat in i18n/uspoof.cpp
INCLUSION & RECOMMENDED in SpoofChecker.java
- make sure that the Unicode Tools tree contains the latest security data files
- go to Unicode Tools org.unicode.text.tools.RecommendedSetGenerator
- run the tool (no special environment variables needed)
cd $UNICODE_TOOLS
mvn -s ~/.m2/settings.xml compile exec:java -Dexec.mainClass="org.unicode.text.tools.RecommendedSetGenerator" \
-Dexec.args="" -am -pl unicodetools -DCLDR_DIR=$(cd ../../../cldr/mine/src ; pwd) -DUNICODETOOLS_REPO_DIR=$(pwd)
- copy & paste from the Console output into the .cpp & .java files
* check hardcoded IDS_Unary_Operator
- new in Unicode 15.1, hardcoded because trivial, and unlikely to change
- check that it has not changed:
(cd $UNICODE_DATA && grep -r --include=PropList.txt IDS_Unary_Operator)
- if it has changed, then update the implementation and the tests
- Since ICU 75, this property is tested in C++ intltest against ppucd.txt.
* check hardcoded ID_Compat_Math_Start & ID_Compat_Math_Continue
- new in Unicode 15.1, hardcoded because trivial, and unlikely to change
- check that they have not changed:
(cd $UNICODE_DATA && grep -r --include=PropList.txt ID_Compat_Math)
- if they have changed, then update the implementation and the tests
- Since ICU 75, these properties are tested in C++ intltest against ppucd.txt.
* Bazel build process
See https://unicode-org.github.io/icu/processes/unicode-update#bazel-build-process
for an overview and for setup instructions.
Consider running `bazelisk --version` outside of the $ICU_SRC folder
to find out the latest `bazel` version, and
copying that version number into the $ICU_SRC/.bazeliskrc config file.
(Revert if you find incompatibilities, or, better, update our build & config files.)
* generate data files
- remember to define the environment variables
(see the start of the section for this Unicode version)
- cd $ICU_SRC
- optional but not necessary:
bazelisk clean
or even
bazelisk clean --expunge
- build/bootstrap/generate new files:
icu4c/source/data/unidata/generate.sh
* Since Unicode 15.1, the UTS #46 data derivation no longer looks at the decompositions (NFD).
These characters are now just valid, no longer disallowed_STD3_valid.
Remove special handling of U+2260, U+226E, U+226F (isNonASCIIDisallowedSTD3Valid())
from uts46.cpp & UTS46.java,
and special test code from uts46test.cpp & UTS46Test.java.
(remove this section next time)
* run & fix ICU4C tests
- Note: Some of the collation data and test data will be updated below,
so at this time we might get some collation test failures.
Ignore these for now.
- fix Unicode Tools class Segmenter to generate correct *BreakTest.txt files
- update CLDR GraphemeBreakTest.txt
cd ~/unitools/mine/Generated

- Robin or Andy helps with RBBI & spoof check test failures
* collation: CLDR collation root, UCA DUCET
- UCA DUCET goes into Mark's Unicode tools,
and a tool-tailored version goes into CLDR, see
https://github.com/unicode-org/unicodetools/blob/main/docs/uca/index.md
- update source/data/unidata/FractionalUCA.txt with FractionalUCA_SHORT.txt
cp -v $CLDR_SRC/common/uca/FractionalUCA_SHORT.txt $ICU4C_UNIDATA/FractionalUCA.txt

(note removing the underscore before "Rules")
cp -v $CLDR_SRC/common/uca/UCA_Rules_SHORT.txt $ICU4C_UNIDATA/UCARules.txt
- restore TODO diffs in UCARules.txt
meld /tmp/UCARules-old.txt $ICU4C_UNIDATA/UCARules.txt
- update (ICU4C)/source/test/testdata/CollationTest_*.txt
and (ICU4J)/main/tests/collate/src/com/ibm/icu/dev/data/CollationTest_*.txt
from the CLDR root files (..._CLDR_..._SHORT.txt)

cp -v $ICU_SRC/icu4c/source/test/testdata/CollationTest_*.txt $ICU_SRC/icu4j/main/tests/collate/src/com/ibm/icu/dev/data
- if CLDR common/uca/unihan-index.txt changes, then update
CLDR common/collation/root.xml <collation type="private-unihan">
and regenerate (or update in parallel) $ICU_SRC/icu4c/source/data/coll/root.txt
- generate data files, as above (generate.sh), now to pick up new collation data
- update CollationFCD.java:
copy & paste the initializers of lcccIndex[] etc. from
ICU4C/source/i18n/collationfcd.cpp to
ICU4J/main/classes/collate/src/com/ibm/icu/impl/coll/CollationFCD.java
- rebuild ICU4C (make clean, make check, as usual)
* Unihan collators
https://github.com/unicode-org/unicodetools/blob/main/docs/unihan.md
- run Unicode Tools GenerateUnihanCollators & GenerateUnihanCollatorFiles,
check CLDR diffs, copy to CLDR, test CLDR, ... as documented there
- generate ICU zh collation data
instructions inspired by
https://github.com/unicode-org/icu/blob/main/tools/cldr/cldr-to-icu/README.txt and
https://github.com/unicode-org/icu/blob/main/icu4c/source/data/cldr-icu-readme.txt

export TOOLS_ROOT=$ICU_SRC/tools
export CLDR_DIR=$CLDR_SRC
export CLDR_DATA_DIR=$CLDR_DIR
(pointing to the "raw" data, not cldr-staging/.../production should be ok for the relevant files)
cd "$TOOLS_ROOT/cldr/lib"

cp /tmp/icu/translit/Hani_Latn.txt icu4c/source/data/translit/Hani_Latn.txt
- rebuild ICU4C
* run & fix ICU4C tests, now with new CLDR collation root data
- run all tests with the collation test data *_SHORT.txt or the full files
(the full ones have comments, useful for debugging)
- note on intltest: if collate/UCAConformanceTest fails, then
utility/MultithreadTest/TestCollators will fail as well;
fix the conformance test before looking into the multi-thread test
* update Java data files
- refresh just the UCD/UCA-related/derived files, just to be safe
- see (ICU4C)/source/data/icu4j-readme.txt
- mkdir -p /tmp/icu4j/com/ibm/icu/impl/data/$ICUDT
- $ICU_OUT/icu4c$ make ICU4J_ROOT=/tmp/icu4j icu4j-data-install
NOTE: If you get the error "No rule to make target 'out/build/icudt70l/uprops.icu'",
you need to reconfigure with unicore data; see the "configure" line above.

It refreshes only the parts of the ICU4J data that we think are affected by a Unicode data update.
It avoids dealing with any other discrepancies

*** API additions
- send notice to icu-design about new born-@stable API (enum constants etc.)
*** CLDR numbering systems
- look for new sets of decimal digits (gc=ND & nv=4) and add to CLDR
for example:
~/icu/mine/src$ egrep ';gc=Nd.+;nv=4' icu4c/source/data/unidata/ppucd.txt > /tmp/icu/nv4-15.txt
~/icu/uni/src$ egrep ';gc=Nd.+;nv=4' icu4c/source/data/unidata/ppucd.txt > /tmp/icu/nv4-15.1.txt

~/unitools/mine/src$ diff -u unicodetools/data/ucd/15.0.0/extracted/DerivedGeneralCategory.txt unicodetools/data/ucd/dev/extracted/DerivedGeneralCategory.txt | grep '; Nd' | egrep '^\+'
-->
(empty this time)
Unicode 15.1:
(none this time)
*** merge the Unicode update branch back onto the main branch
- do not merge the icudata.jar and testdata.jar,
instead rebuild them from merged & tested ICU4C
- if there is a merge conflict in icudata.jar, here is one way to deal with it:
+ remove icudata.jar from the commit so that rebasing is trivial
+ ~/icu/uni/src$ git restore --source=main icu4j/main/shared/data/icudata.jar
+ ~/icu/uni/src$ git commit -a --amend
+ switch to main, pull updates, switch back to the dev branch
+ ~/icu/uni/src$ git rebase main
+ rebuild icudata.jar
+ ~/icu/uni/src$ git commit -a --amend
+ ~/icu/uni/src$ git push -f

- if they have changed, then update the implementation and the tests
- TODO: There is a ticket for using ppucd.txt in test code.
Do that and check these hardcoded properties against that.
- Since ICU 75, these properties are tested in C++ intltest against ppucd.txt.
