Error sending html email with mailgun python API

问题

I can send text email with the Mailgun python API fine:

def send_simple_message(mailtext, filename=""):
  requests.post("https://api.mailgun.net/v3/mydomain.in/messages",
  auth=("api", "key-1234"),
  files=[("attachment", open(filename))],
  data={"from": "Credit Card Manager <creditcards@mydomain.in>",
  "to": ["bob@mydomain.in"],
  "subject": "Summary of Credit Card payments due",
  "text": mailtext})

The above code works fine, and message is delivered.

However when I try the following, using an html string,

def send_simple_message(mailtext, mailhtml, filename=""):
  requests.post("https://api.mailgun.net/v3/mydomain.in/messages",
  auth=("api", "key-61a652b57"),
  files=[("attachment", open(filename))],
  data={"from": "Credit Card Manager <creditcards@mydomain.in>",
  "to": ["bob@mydomain.in"],
  "subject": "Summary of Credit Card payments due",
  "text": mailtext,
  "html": mailhtml})

where, mailhtml is the following string:

<html><body><h4>CREDIT CARD STATEMENT FOR MAY</h4><table><tr><th>Card</th><th>Dues</th><th>Date</th></tr><tr><td>Standard Chartered</td><td>3,755.29</td><td>16/05/2018</td></tr><tr><td>HDFC</td><td>41,616.90</td><td>04/05/2018</td></tr><tr><td>ICICI</td><td>5,833.74</td><td>11/05/2018</td></tr><tr><td>SBI</td><td>20,667.00</td><td>01/05/2018</td></tr></table></body></html>

I get the following error:

    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 0: invalid continuation byte

What seems to be the problem here?
