This Lua module is used on approximately 512,000 pages, or roughly 1% of all pages.

The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them.

This module contains data that is used by Module:Unicode data to determine the Unicode script code for a code point and to determine if a Unicode script is written right-to-left. The right-to-left script data is sourced from Module:Lang/data. The main table in the module is generated by Module:Unicode data/scripts/make from Scripts.txt and PropertyValueAliases.txt in the Unicode Character Database (version 15.1).
