Questions tagged [quoted-printable]

A widely used email encoding that represents all bytes as printable 7-bit ASCII characters using `=` as the escape character, while also limiting line length to 76.

From https://en.wikipedia.org/wiki/Quoted-printable (slightly edited):

Quoted-Printable, or QP encoding, is an encoding using printable ASCII characters [...] to transmit 8-bit data over a 7-bit data path or, generally, over a medium which is not 8-bit clean.

It is defined as a MIME content transfer encoding for use in e-mail. QP works by using the equals sign = as an escape character.

It also limits line length to 76, as some software has limits on line length.

Quoted-Printable is efficient and reasonably human-readable only for input text with mostly 7-bit ASCII characters, such as English text.
