This library deals with decoding and encoding Quoted-Printable text.
Very briefly explained, qp encoding means translating all 8-bit characters (and lots of control characters) into things that look like ‘=EF’; that is, an equal sign followed by the byte encoded as a hex string.
The following functions are defined by the library:
