transcode - node__buffer.d.ts - Node

function transcode

Usage in Deno

```typescript import { transcode } from "node:node__buffer.d.ts"; ```



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: ```js 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
