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:
quoted-printable-decode-region ¶QP-decode all the encoded text in the specified region.
quoted-printable-decode-string ¶Decode the QP-encoded text in a string and return the results.
quoted-printable-encode-region ¶QP-encode all the encodable characters in the specified region. The third optional parameter fold specifies whether to fold long lines. (Long here means 72.)
quoted-printable-encode-string ¶QP-encode all the encodable characters in a string and return the results.
