What is Base64?
Base64 represents binary data using 64 printable ASCII characters. It is used to embed images in CSS/HTML as data URIs, send attachments in email and pass binary data through JSON or URLs.
Does it support Unicode?
Yes. Text is encoded as UTF-8 first, so emoji and non-Latin scripts round-trip correctly.
