Base64 Valid Charachter To Encode
Which charachters are encodable for base64? It is possible to create a text unencodable with base64?
Base64 encoding takes groups of 3 bytes (3 x 8 = 24 bits) and converts them to 4 x 6 bits (also 24 bits).
Since the conversion happens on the binary data, all data (including all characters) can be encoded.
