Module:Unicode data/category/doc

Unicode General Category data derived from DerivedGeneralCategory.txt in the Unicode Character Database.

The data was generated by the two Lua 5.3 scripts below. LPeg is required. If the two scripts are in the same folder as DerivedGeneralCategory.txt, all one has to do is go to the directory with the command line and type lua print_data.lua to print the data to data.lua.
