False encoding of iOS emails

[J04n5mith]

If you send an email to the bot from an iOS device it encodes false.

This text:
4 kontis (2 m mit Mütze, 1 m mit Bart und 1 w älter) am Rathenauplatz Richtung Bahnhof.

Encodes to this:
4 kontis (2 m mit M=C3=BCtze, 1 m mit Bart und 1 w =C3=A4lter) am Rathenaupl=
atz Richtung Bahnhof.=20

Looks like a strange ASCII representation of UTF-8 encoding, where % is sometimes (?) replaced with =.
Might be related to #27

I've found what it is!
It's the wrong encoding! Or rather it's the quoted printable version of the utf-8 string.
we could implement something like this to fix future encoding errors in email reports.
