The "Q" means it uses the encoding known as "quoted-printable". This
and Base64 are the usual encodings in MIME. QuotedPrintable is simpler
and results in longish encoded strings, being suitable for texts with
a few characters out of ASCII 7-bit range.

From  "[SUMMARY] Quoted Printable (#23)"
(http://ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-talk/133976) sent to
this mailing list,

class String
 def to_quoted_printable(*args)
   [self].pack("M").gsub(/\n/, "\r\n")
 end
 def from_quoted_printable
   self.gsub(/\r\n/, "\n").unpack("M").first
 end
end

provides the solution you want. Just try:

         s = "Jes=FAs_=C1ngel";
         print s.from_quoted_printable

Cheers,
Adriano.
