Decode Numeric Character References

This feature allows you to decode numeric character references (e.g., 😀) into their corresponding characters (e.g., 😀). The code sample demonstrates decoding a hexadecimal numeric character reference.

const decode = require('micromark-util-decode-numeric-character-reference');

const input = '😀';
const output = decode(input);
console.log(output); // 😀

This feature ensures that invalid numeric character references are handled gracefully by returning a replacement character (�). The code sample demonstrates decoding an invalid hexadecimal numeric character reference.

const decode = require('micromark-util-decode-numeric-character-reference');

const input = '&#xZZZZ;';
const output = decode(input);
console.log(output); // �
