API

This module exports a single function named matchPropertyValue.

matchPropertyValue(property, value)

This function takes a string property that is a canonical/unaliased Unicode property name, and a string value. It attemps to match value to a canonical Unicode property value for the given property. If there’s a match, it returns the canonical property value. Otherwise, it throws an exception.

// Find the canonical property value:
matchPropertyValue('Block', 'Alphabetic_PF')
// → 'Alphabetic_Presentation_Forms'

matchPropertyValue('Block', 'Alphabetic_Presentation_Forms')
// → 'Alphabetic_Presentation_Forms'

matchPropertyValue('block', 'Alphabetic_PF') // Note: incorrect casing.
// → throws

matchPropertyValue('Block', 'alphabetic_pf') // Note: incorrect casing.
// → throws
