Node.js module to fix ISO-8859-1 (Latin-1) and Windows-1252 (CP1252) mojibake in UTF-8 strings

Decoding UTF-8 bytes as ISO-8859-1 (Latin-1) or Windows-1252 (CP1252) leaves ASCII intact but turns every non-ASCII character into mojibake, where ’ becomes ’.

The fix-latin1-to-utf8 module restores the original characters for both character encodings, including text garbled more than once. Text resembling mojibake is left unchanged, so some Cyrillic and Chinese text may not be restored.

Install using npm:

npm i fix-latin1-to-utf8

Please refer to the JSDoc comments in the source code or the generated type definitions for information on the available options.

"use strict";

const fixLatin1ToUtf8 = require("fix-latin1-to-utf8");

const mojibakeString = "The café’s sign was garbled.";
const fixedString = fixLatin1ToUtf8(mojibakeString);

console.log(fixedString);
// The café’s sign was garbled.
