@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.

Returns the canonical combining class for the given code point.
getEastAsianWidth(codePoint)
Returns the East Asian width for the given code point.
getNumericValue(codePoint)
