Below are scripts I use for maintaining the Unicode database at Module:Unicode data.

How to use scripts on this page

Ingredients: GNU Make, GNU awk, GNU wget.

Put the scripts below in a dedicated directory.
Run make clean, then make.
The Unicode database will be downloaded, and several .lua files will be generated from it. Save them in appropriate locations as specified in the table below.
Update the Unicode version number wherever you find it (e.g. Module:character list)
Done. Throw a drinking party.

File name	Wiktionary page
`aliases.lua`	Module:Unicode data/aliases
`blocks.lua`	the `blocks` table in Module:Unicode data
`combining.lua`	Module:Unicode data/combining
`control.lua`	Module:Unicode data/control (includes Cx and Zx)
`names_XXX.lua`	Module:Unicode data/names/`XXX`
