// Examples:
const Lu = require('regenerate-unicode-properties/General_Category/Uppercase_Letter.js').characters;
const Greek = require('regenerate-unicode-properties/Script_Extensions/Greek.js').characters;

For maintainers

How to publish a new release

  1. On the main branch, bump the version number in package.json:

     npm version patch -m 'Release v%s'

    Instead of patch, use minor or major as needed.

    Note that this produces a Git commit + tag.

  2. Push the release commit and tag:

     git push && git push --tags

    Our CI then automatically publishes the new release to npm.
