UnicodeDecodeError: While reading a csv file using .csvreader - pandas

Question

Here's my code:
import csv
path = "/home/Downloads/sample_email.csv"
with open(path) as csvfile:
reader = csv.DictReader(csvfile)
for row in reader:
print(row['first_name'], row['last_name'])
The error is:
UnicodeDecodeError Traceback (most recent call last)
<ipython-input-47-d89ea200a227> in <module>
3 with open(path) as csvfile:
4 reader = csv.DictReader(csvfile)
----> 5 for i in reader:
6 print(i['first_name'], i['last_name'])
/usr/lib/python3.6/csv.py in __next__(self)
109 if self.line_num == 0:
110 # Used only for its side effect.
--> 111 self.fieldnames
112 row = next(self.reader)
113 self.line_num = self.reader.line_num
/usr/lib/python3.6/csv.py in fieldnames(self)
96 if self._fieldnames is None:
97 try:
---> 98 self._fieldnames = next(self.reader)
99 except StopIteration:
100 pass
/usr/lib/python3.6/codecs.py in decode(self, input, final)
319 # decode input (taking the buffer into account)
320 data = self.buffer + input
--> 321 (result, consumed) = self._buffer_decode(data, self.errors, final)
322 # keep undecoded input until the next call
323 self.buffer = data[consumed:]
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 596: invalid start byte
When i want to convert this file to df, i have to use :
df = pd.read_csv(path, sep=',', engine = 'python')
Any help?
My aim is , extract the data, and a create a email template. Any guide about this matter is also appriciated.
