Quoted-Printable is a MIME content transfer encoding defined in RFC 2045, primarily used for email transmission. It allows text containing non-ASCII characters (like accented letters, special symbols, or Unicode characters) to be safely transmitted through email systems that only support 7-bit ASCII. It is commonly used in email headers and body content.
Quoted-Printable keeps ASCII printable characters (33-126, except =) unchanged, making the encoded text mostly human-readable. Non-printable and non-ASCII characters are encoded as =XX where XX is the hexadecimal value of the byte. The equals sign itself becomes =3D. Lines are wrapped at 76 characters using soft line breaks (= at end of line).
Quoted-Printable is designed for text that is mostly ASCII, keeping readable characters unchanged while encoding only special characters. Base64 encodes all data uniformly, making it unreadable but more compact for binary data. Quoted-Printable is better for email text content, while Base64 is preferred for attachments and binary data.
