[dev-context] How up to date char-def.lua is?

Since Unicode keeps adding new characters and scripts with each release (and some times altering the properties of existing characters), I was wondering how up to date char-def.lua is, in particular on which version of Unicode data was it based and how frequently it is synced with Unicode (if at all). It would be even nice to have an mtx script to update the database when needed. Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
