@react-pdf/unicode-properties

Provides fast access to unicode character properties. Uses unicode-trie to compress the properties for all code points into just 12KB.

Acknowledges

This project is a fork of unicode-properties by @devongovett and continued under the scope of this project since it has react-pdf specific features. Any recongnition should go to him and the original project mantainers.
