Quoted printable decoding is not correct in a few cases

[devconcept]

If you decode this sequence

=E2=80=A6

You should get this character "…"

Instead you get "�"

Which is obviously not the right output. I succeeded in converting it using decodeURIComponent(escape(input)) but this options doesn't work all the time because, I think, should only be applied in some cases.

What I am missing here?

This sequence decodes with errors too

=C2=B7

You should get "·" and instead you get "·"

The Content-Type of your mime part is missing, should be something like text/plain; charset=utf-8

[devconcept]

It is utf-8 and it doesn't work

Can you provide the full MIME node?
