Good to know
Encode text as UTF-8 bytes using standard Base64, or decode Base64 back to UTF-8 text. Whitespace in encoded input is ignored. Decoding requires standard + and / characters and any required = padding; URL-safe Base64 is not supported here. Invalid encodings and non-UTF-8 bytes produce an error. Base64 is an encoding, not encryption.
Example: Hello becomes SGVsbG8=. Accented letters, non-Latin scripts and emoji work too.
