Python中的UnicodeError

Question

从我的脚本输出数据时遇到问题：

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 14: ordinal not in range(128)

这是输出数据的代码：

zipped = zip(list_1, list_2, list_3, list_4, list_5)

with open('my_file.csv', 'rb') as infile, open('my_out_file.csv', 'wb') as outfile:
reader = csv.reader(infile)
writer = csv.writer(outfile)
for i, row in enumerate(reader):
    row.extend(zipped[i])
    writer.writerow(row)

经过一番搜索，我意识到我必须手动将其编码为UTF8，但我无法弄清楚如何。任何帮助表示赞赏。
