The quote-printable (qP) method is usually abbreviated as "Q". The principle isThe 8-bit character is represented by two hexadecimal values, and "=" is added to the front ". So we can see that it is encoded by QP.The following file is usually like

Quoted-printable is also one of the common encoding methods in mime mail. Like base64, it also encodes the input string or data into printable ASCII strings. Quoted-printable: the input data is in the range of 33-60 and 62-126 and is directly output;

The quopri and base64 modules are both used for encoding and decoding, and base64 and quoted-printable are both common encodings in emails. Quoted-printable: The English character is not processed except =. The other characters are encoded as = The

Introduction"Character and encoding" is a frequently discussed topic. Even so, garbled characters often plague everyone. Although we have many ways to eliminate garbled characters, we do not necessarily understand the internal principles of these
