Map of invalid numeric character references to their replacements, according to HTML
Package description
The character-reference-invalid npm package provides utilities for handling invalid character references in HTML and XML documents. It is primarily used to encode and decode invalid characters to ensure that text is safely and correctly processed in web applications and other environments that handle HTML/XML content.
Decoding invalid character references
This feature allows the decoding of invalid character references into their respective Unicode representations, which is useful for processing or sanitizing input data in web applications.
const cri = require('character-reference-invalid');
console.log(cri.decode('�')); // Outputs: \\uD800Encoding characters to invalid references
This feature enables the encoding of characters into their equivalent invalid character references. This is particularly useful when you need to generate HTML or XML output that includes characters that might otherwise be handled incorrectly by some parsers.
const cri = require('character-reference-invalid');
console.log(cri.encode(String.fromCodePoint(0xD800))); // Outputs: '�'The 'he' package is an HTML entity encoder/decoder. Unlike character-reference-invalid, which focuses on invalid character references, 'he' deals with all HTML entities, providing a broader scope of functionality for encoding and decoding HTML content.
Similar to 'he', the 'entities' package provides comprehensive support for encoding and decoding HTML entities. It offers more extensive support compared to character-reference-invalid, which is specialized in handling invalid references.
Readme
Map of invalid numeric character references to their replacements, according to HTML.
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 12.20+, 14.14+, or 16.0+), install with npm:

</script>
import {characterReferenceInvalid} from 'character-reference-invalid'
console.log(characterReferenceInvalid[0x80]) // => '€'
console.log(characterReferenceInvalid[0x89]) // => '‰'
console.log(characterReferenceInvalid[0x99]) // => '™'
