Unicode [[General Category]] data derivedgenerated by [[Module:Unicode data/category/make]] from [https://www.unicode.org/Public/UNIDATA/extracted/DerivedGeneralCategory.txt DerivedGeneralCategory.txt] and [https://unicode.org/Public/UNIDATA/PropertyValueAliases.txt PropertyValueAliases.txt] in the Unicode Character Database. The category Cn (Unassigned) is omitted because it is the default for characters not assigned to another category.
The data was generated by the two Lua 5.3 scripts below. [http://www.inf.puc-rio.br/~roberto/lpeg/lpeg.html LPeg] is required. If the two scripts are in the same folder as <code>DerivedGeneralCategory.txt</code>, all one has to do is go to the directory with the command line and type <code>lua print_data.lua</code> to print the data to <code>data.lua</code>.
