= Quoted-printable = '''Quoted-printable''' is an encoding of binary data within printable 7-bit characters. <> ---- == Structure == A quoted-printable file leaves all printable 7-bit ASCII characters alone. For 8-bit characters, an equals sign (`=`) is used as an escape character, indicating that the subsequent 2 characters should instead be interpretted as a hexadecimal value representing the true character. Literal equals signs must be escaped as `=3D`. Quoted-printable files must not exceed 76 characters. If a line must be broken in order to satisfy this requirement, a soft break is introduced by ending the line with a lone equals sign (`=`). == History == Quoted-printable emerged as an improvement upon [[Email/Uuencoding|uuencoding]]. It is a method for sending binary or UTF-8 data through [[Email/MTA|message transfer agents]] that do not respect character encodings and character sets. A quoted-printable file is roughly legibile by humans while still being resilient to poor message handling. ---- CategoryRicottone
