Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2022.

The readable read-only property of the TextDecoderStream interface returns a ReadableStream that emits decoded strings.
Value
Examples
This example creates a TextDecoderStream that decodes UTF-8 encoded binary data. It writes some encoded binary data to the writable stream, then reads the decoded text from the readable stream.
js
const stream = new TextDecoderStream();
// Write data to be decoded
const data = Uint8Array.fromBase64("5L2g5aW95LiW55WM");
const writer = stream.writable.getWriter();
writer.write(data);
writer.close();
// Read decoded data
const reader = stream.readable.getReader();
let done = false;
let output = "";
while (!done) {
const result = await reader.read();
if (result.value) {
output += result.value;
}
done = result.done;
}
console.log(output); // 你好世界
