+description: Modern alternatives to the utf8 package for UTF-8 encoding and decoding
+---
+
+# Replacements for `utf8`
+
+Modern Node and browsers provide native UTF-8 APIs, so this dependency is rarely needed.
+
+## TextEncoder/TextDecoder (built-in)
+
+The built-in [`TextEncoder`](https://developer.mozilla.org/en-US/docs/Web/API/TextEncoder) and [`TextDecoder`](https://developer.mozilla.org/en-US/docs/Web/API/TextDecoder) APIs provide a native way to handle UTF-8 encoding and decoding.
+
+```ts
+const text = "€";
+const encoder = new TextEncoder();
+const utf8Bytes = encoder.encode(text); // Uint8Array of UTF-8 bytes
+
+// and to decode:
+
+const decoder = new TextDecoder('utf-8', { fatal: true });
+const decodedText = decoder.decode(utf8Bytes); // "€"
+```
+
+## Buffer (Node.js)
+
+Node's built-in [`Buffer`](https://nodejs.org/api/buffer.html) provides both `Buffer.from(str, 'utf8')` and `buf.toString('utf8')` methods for UTF-8 encoding and decoding.
+
+```ts
+const text = "€";
+const utf8Buffer = Buffer.from(text, 'utf8'); // Buffer of UTF-8 bytes
+```
