How we handle Unicode
Base64 is a format for encoding bytes, not strings, so there isn't exactly a standard for encoding non-ASCII characters. Here we assume everything you paste is UTF-8 and was gone through URI-encoding to make an ASCII representation. It is quite standard approach and for example, Mac's base64 utility behaves the same way.
