The Nuances of Base64 Encoding Strings in JavaScript

The article explains that JavaScript’s native btoa() and atob() functions only handle ASCII, so to correctly base64‑encode Unicode strings you must convert them with TextEncoder to UTF‑8 bytes, use Uint8Array, and decode with TextDecoder, while checking for malformed surrogate pairs via isWellFormed or encodeURIComponent to avoid silent data loss.
