transcode - buffer - Node

function transcode

Usage in Deno

import { transcode } from "node:buffer";



transcode(source: Uint8Array,
fromEnc: TranscodeEncoding,
toEnc: TranscodeEncoding,
): Buffer

Re-encodes the given Buffer or Uint8Array instance from one character encoding to another. Returns a new Buffer instance.

Throws if the fromEnc or toEnc specify invalid character encodings or if conversion from fromEnc to toEnc is not permitted.

Encodings supported by buffer.transcode() are: 'ascii', 'utf8', 'utf16le', 'ucs2', 'latin1', and 'binary'.

The transcoding process will use substitution characters if a given byte sequence cannot be adequately represented in the target encoding. For instance:

import { Buffer, transcode } from 'node:buffer';

const newBuf = transcode(Buffer.from('€'), 'utf8', 'ascii');
console.log(newBuf.toString('ascii'));
// Prints: '?'

Because the Euro (€) sign is not representable in US-ASCII, it is replaced with ? in the transcoded Buffer.

Parameters



source: Uint8Array

A Buffer or Uint8Array instance.



fromEnc: TranscodeEncoding

The current encoding.



toEnc: TranscodeEncoding

To target encoding.

Return Type

Buffer
