[issue17495] email.quoprimime.body_encode can't handle characters that encodings.quopri_codec can

[Ross Patterson]

New submission from Ross Patterson:

When using email.charset.Charset to encode MIME bodie as quoted-printable, some characters that are encodable with the quopri_codec cause a KeyError in email.quoprimime:

>>> text_encoded = b'mo \xe2\x82\xac'
>>> text = text_encoded.decode('utf-8')
>>> print(text)
mo €
>>> import codecs
>>> codecs.getencoder('quopri_codec')(text_encoded)[0]
b'mo=20=E2=82=AC'
>>> from email import charset
>>> c = charset.Charset('utf-8')
>>> c.header_encoding = charset.QP
>>> c.body_encoding = charset.QP
>>> c.header_encode(text)
'=?utf-8?q?mo_=E2=82=AC?='
>>> c.body_encode(text)
