API

This module exports a single function named matchLoosely.

`matchLoosely(propertyInput, [valueInput])`

This function takes two strings propertyInput and valueInput and applies loose matching on the property-value pair within the list of all Unicode property values. valueInput is optional.

The return value is an object containing containing the canonical property name property and the canonical property value name value. If an unknown propertyInput is given, an exception is thrown.

// Find the canonical property name and property value name:
matchLoosely('blk', 'Arabic_PF_B')
// → { 'property': 'Block', 'value': 'Arabic_Presentation_Forms_B' }

// Find the canonical property name:
matchLoosely('compex')
// → { 'property': 'Full_Composition_Exclusion' }
