@aws-sdk/util-utf8

What is @aws-sdk/util-utf8?

@aws-sdk/util-utf8 is a utility package from AWS SDK for JavaScript that provides functions to encode and decode UTF-8 strings. It is particularly useful when working with AWS services that require UTF-8 encoding.

What are @aws-sdk/util-utf8's main functionalities?

UTF-8 Encoding

This feature allows you to encode a string into UTF-8 format. The `toUtf8` function takes a string as input and returns its UTF-8 encoded version.

const { toUtf8 } = require('@aws-sdk/util-utf8');
const utf8Encoded = toUtf8('Hello, World!');
console.log(utf8Encoded);

UTF-8 Decoding

This feature allows you to decode a UTF-8 encoded array back into a string. The `fromUtf8` function takes a Uint8Array as input and returns the decoded string.

const { fromUtf8 } = require('@aws-sdk/util-utf8');
const utf8Decoded = fromUtf8(new Uint8Array([72, 101, 108, 108, 111, 44, 32, 87, 111, 114, 108, 100, 33]));
console.log(utf8Decoded);
