Base64 Encoder/Decoder
Encode text to Base64 or decode Base64 back to text, with full UTF-8 support.
Encode text to Base64 or decode Base64 back to text, with full UTF-8 support.
How to use
Encoding converts the UTF-8 bytes of the text to Base64, so emoji and non-Latin scripts survive the round trip. Decoding reverses the process and rejects input that is not valid Base64-encoded UTF-8.
Example
Encoding "Hello, 世界" produces "SGVsbG8sIOS4lueVjA==", which decodes back to the original text.
