(These last are + only in the zip, not in the web-space's unpacked versions.) +* If needed, add an entry to enum QChar::UnicodeVersion for the new + Unicode version +* In that case, also update main.cpp's initAgeMap and DATA_VERSION_S* + to match +* Build this project. Its binary, unicode, ignores command-line + options and assumes it is being run from this directory. When run, + it produces lots of output. Hopefully that doesn't matter. +* Assertions may trigger: if so, study code and understand what's more + complicated about this update; talk to folk named in the git logs, + maybe push a WIP to gerrit to solicit advice. Some bit-field may + need to be expanded, for example. In some cases QChar may need + additions to some of its enums. +* Build with the modified code, fix any compilation issues. +* That may have updated qtbase/src/corelib/tools/qunicodetables.cpp; + if so the update matters; be sure to commit the changes to data/ at + the same time and update tools/qt_attribution.json to match; use the + UCD Revision number, rather than the Unicode standard number, as the + Version, for all that qunicodetables.cpp uses the latter. + +The script writingSystems.sh generates a list of writing systems, +ostensibly as a the basis for updating QFontDatabase::WritingSystem +enum; however, the Release 20 output of it contains many more writing +systems than are present in that enum, suggesting it has not been run +in a very long time.
