Section 4.5 says:
For example, a form with a text field in which a user typed "Joe owes <eu>100", where <eu> is the Euro symbol, might have form data returned as: --AaB03x content-disposition: form-data; name="field1" content-type: text/plain;charset=UTF-8 content-transfer-encoding: quoted-printable Joe owes =E2=82=AC100. --AaB03x
It should say:
For example, a form with a text field in which a user typed "Joe owes <eu>100", where <eu> is the Euro symbol, might have form data returned as: --AaB03x content-disposition: form-data; name="field1" content-type: text/plain;charset=UTF-8 content-transfer-encoding: quoted-printable Joe owes <eu>100. --AaB03x
Notes:
Section 4.7 says that "Senders SHOULD NOT generate any parts with a Content-Transfer-Encoding header field."
