Today I received an e-mail, which contained something completely unreadable.

When using Windows, I get used to use the "Stirlitz" utility (ru.wikipedia.org) to automatically decrypt mojibake (or "krakozyabry" as we call the stuff in Russian).
As far as I know, all these equal signs, "A"s, "B"s, "C"s, etc., are used in the so called "Quoted-printable" encoding.
At my OpenSUSE 11.2 I found a small utility called recode that is well suitable to solve the task. I saved an e-mail as 66.eml and pipelined it to recode. The latter successfully decoded QP into UTF-8:
$> cat 66.eml | recode /qp
