About the Quoted-Printable Encoder

Quoted-printable is the MIME encoding that keeps mostly-text content readable while still surviving a mail path that only guarantees seven bits. Printable ASCII passes through untouched; everything else becomes an equals sign followed by two hex digits.

It is the reason a raw email source is full of =C3=A9 and lines ending in a bare equals sign. That trailing equals is a soft line break, inserted because quoted-printable lines cannot exceed 76 characters — the decoder removes it and rejoins the line. Decoding is what you need when reading a raw message, a bounce report or a header; encoding is what you need when composing one by hand or testing a mail pipeline.

Key features of the Quoted-Printable Encoder

Soft line breaks handled

Lines are wrapped at the RFC limit with a trailing equals, and decoding rejoins them — which is what makes a raw email body readable again.

Trailing whitespace protected

A space or tab before a line break is encoded as =20 or =09, because mail transport is allowed to strip it otherwise.

Full UTF-8

Accented characters and emoji are encoded byte by byte and decode back exactly.

Escape sequences never split

A =XX sequence is never broken across a line boundary, which would make it undecodable.

Configurable line length

76 is the standard, and lower values are available for pipelines with stricter limits.

Frequently asked questions

It is a soft line break. Quoted-printable lines cannot exceed 76 characters, so a long line is split and the equals tells the decoder to rejoin it with no break.
