FAQ
What is Quoted-Printable encoding?
An encoding (defined in RFC 2045) mainly used in email (MIME) that represents non-ASCII or non-printable bytes as =XX hex sequences, while keeping most printable ASCII text readable as-is.
Why are long lines split with a trailing "="?
Quoted-Printable limits lines to 76 characters for compatibility with older email systems. A "=" at the end of a line is a soft line break, meaning the line continues without inserting an actual newline.
Where is Quoted-Printable still used?
Primarily in email message bodies and headers (MIME), especially for content that needs to stay mostly human-readable while safely handling accented characters and special bytes.
Does this handle Unicode text?
Yes - text is encoded as UTF-8 bytes first, so multi-byte characters like accented letters or emoji are correctly represented as multiple =XX sequences.
