This is a map from the HTML spec of C1 ASCII/Unicode control characters (which are disallowed by HTML) to the characters those code points would have in Windows 1252. For example, U+0080 (Padding Character) maps to €, because that’s used for 0x80 in Windows 1252.

Probably never, unless you’re dealing with parsing HTML or similar XML-like things, or in a place where Unicode is not the primary encoding (it is in most places).

This package is ESM only. In Node.js (version 14.14+, 16.0+), install with npm:

  import {characterReferenceInvalid} from 'https://esm.sh/character-reference-invalid@2?bundle'
</script>

import {characterReferenceInvalid} from 'character-reference-invalid'

console.log(characterReferenceInvalid[0x80]) // => '€'
console.log(characterReferenceInvalid[0x89]) // => '‰'
console.log(characterReferenceInvalid[0x99]) // => '™'
