title: convert/decode a mail "quoted-printable" string from a variable with javax.mail.internet.MimeUtility or an other way?
body: <p>I have a text content of an .eml file that I put in a variable and I would parse its content, including converting different formats.
  If in the header an "quoted-printable" string have surrounded tags =? Utf-8? Q? ....? =
  the mimeUtlility.decodeText () function works well, but if I have a coded text "quoted-printable" in the body of the email without these tags, mimeUtlility.decodeText () of javax.mail.internet.MimeUtility does not.
  How can I decode these texts of different formats and charsets?
    an example of a portion of text: "Cell Manager
           S = = E9 E9curit / Pr = E9vention / Suret = E9 "
  and sometimes there are "=CRLF" at end of lines</p>
