Как правильно декодировать строку из 866 в UTF8, полученную из консоли дочернего процесса.

ChildProcess.exec.ts

async function exec(command) {
	const from = '866', to = 'utf8';
	const exec = Util.promisify(ChildProcess.exec);
	const {stdout, stderr} = await exec(command, {encoding: 'buffer'});
	return {
		stdout: Encoding.convert(stdout, to, from).toString(to),
		stderr: Encoding.convert(stderr, to, from).toString(to)
	};
};
const {stdout, stderr} = await exec(`dir`);

import.ts

import * as ChildProcess from 'child_process';
import * as Util from "util";
import * as Encoding from "encoding";

saveToTempFile.ts

import * as Os from "os";
import * as Path from "path";

const tempFilePath = Path.join(Os.tmpdir(), '@TEMP', 'temp.txt');
await writeFile(tempFilePath, stdout);
console.log(stdout)
