Quoted-printable

Quoted-printable is an encoding method defined in the MIME standard. It is used primarily to encode 8-bit text (such as text that includes foreign characters) into 7-bit US ASCII, creating a document that is mostly readable by humans, even in its encoded form. All MIME-compliant applications can decode quoted-printable text, though they may not necessarily be able to properly display the document as it was originally intended.

What is the decoded message of the text that has been encoded using Quoted-printable encoding inside the file?
