Overview

tc-lib-unicode-data is a data-centric package that provides Unicode lookup tables, mappings, and constants consumed by tc-lib-unicode and related libraries.

It externalizes large Unicode datasets into a dedicated package so runtime libraries can stay focused on algorithms instead of data distribution. Versioned data updates also become easier to manage and review as Unicode standards evolve.

Features

Data Coverage

• Unicode property and identity constants
• Script/category mapping data
• Bracket, mirroring, and shaping-related tables

Integration Role

• Runtime dependency for higher-level Unicode processing
• Pure data distribution, no heavy runtime logic
• Deterministic, versioned updates

Requirements

• PHP 8.2 or later
• Composer
