UnicodeTools

ECMAScript modules which implement some of the Unicode® Standard.

Currently, only the default/canonical case folding (the Unicode® Standard 12.0.0, section 3.13, R4/D145) is implemented.

New functionalities may be added on (author's) demand in future.

Installation

npm install @kkitahara/unicode-tools

Examples

import { toCaseFold } from '@kkitahara/unicode-tools'

'\u{00c5}' === '\u{00e5}' // false
toCaseFold('\u{00c5}') === '\u{00e5}' // true

'\u{0041}\u{030a}' === '\u{0061}\u{030a}' // false
toCaseFold('\u{0041}\u{030a}') === '\u{0061}\u{030a}' // true

// return the input value if it is not a string
toCaseFold(null) // null
toCaseFold(false) // false

import { toCanonicalCaseFold } from '@kkitahara/unicode-tools'

'\u{00c5}' === '\u{00e5}' // false
