-# boa-unicode
+# DEPRECATED
 
-`boa-unicode` defines the trait to provide methods for querying properties or classes for Unicode identifiers. These properties are used to determine if a code point (char) is valid for being the start/part of an identifier in lexer and parser.
-
-Current version: Unicode 15.0.0
-
-## Development
-
-The Unicode character tables used to query properties are generated by `build_tables.js`. This script depends on [Node.js](https://nodejs.org/en/) and [rustfmt](https://github.com/rust-lang/rustfmt). You can run the script with:
-
-```
-$ node build_tables.js
-```
-
-or with [npm](https://www.npmjs.com/):
-
-```
-$ npm run build-tables
-```
-
-The configurations are defined as constants in the script. Please check the comments in `build_tables.js` for more information.
