Python 3:UnicodeEncodeError:'；ascii'；编解码器可以'；t编码字符'\u0142'；在位置111：序号不在范围内（128）

我是Python的新用户

我正在尝试编写脚本，它将帮助我通过我的gmail帐户发送电子邮件。Python从.xlsx文件读取数据，并从excel列表向用户发送消息

在我尝试发送带有波兰语字符的电子邮件之前，一切都正常。 在我的excel电子表格中使用波兰语字符时也会出现同样的问题

我试图使用“编码：utf-8”信息，但它不起作用

我的代码：

# -*- encoding: utf-8 -*-
#! python3

# sendDuesReminders.py - Sends emails based on payment status in
spreadsheet.


import openpyxl, smtplib, sys


# Open the spreadsheet and get the latest dues status.

wb = openpyxl.load_workbook('duesRecords.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')

lastCol = sheet.max_column
latestMonth = sheet.cell(row=1, column=lastCol).value


# Check each member's payment status.

unpaidMembers = {}
for r in range(2, sheet.max_row + 1):
    payment = sheet.cell(row=r, column=lastCol).value
    if payment != 'zaplacone':
        name = sheet.cell(row=r, column=2).value
        lastname = sheet.cell(row=r, column=3).value
        email = sheet.cell(row=r, column=4).value
        school = sheet.cell(row=r, column=6).value
        rate = sheet.cell(row=r, column=7).value
        unpaidMembers[name] = lastname, email, school, rate



# Log in to email account.

smtpObj = smtplib.SMTP_SSL('smtp.gmail.com', 465)
smtpObj.ehlo()
# smtpObj.starttls()
smtpObj.login('xxx@xxx.com', '')



# Send out reminder emails.
for name, (lastname, email, school, rate) in unpaidMembers.items():
     body = "Subject: %s - przypomnienie o platnosci raty za treningi GIT Parkour. " \
         "\n\nPrzypominamy o uregulowaniu wpłaty za uczestnictwo: %s %s w treningach GIT Parkour w %s." \
         "\n\nWplata dotyczy okresu: %s." \
         "\n\n\nProsimy o uregulowanie platnosci w kwocie %szl na konto:" \
         "\nJESTEM GIT" \
         "\nJ.Klos, M.Kolodziejczyk s.c." \
         "\nul. Grunwaldzka 609d/17, Gdansk" \
         "\nAlior Bank - 36 2490 0005 0000 4500 1296 0191" \
         "\n\n\nPozdrawiamy," \
         "\nGIT Trenerzy."%(latestMonth, name, lastname, school, latestMonth, rate)
    print('Sending email to %s...' % email)
    sendmailStatus = smtpObj.sendmail('xxx@xxx.com', email, body)

    if sendmailStatus != {}:
        print('There was a problem sending email to %s: %s' % (email,
        sendmailStatus))
smtpObj.quit()

我收到的错误是：

Traceback (most recent call last):
  File "sendDuesEmailReminder.py", line 57, in <module>
    sendmailStatus = smtpObj.sendmail('xxx@xxx.com', email, body)
  File "/Users/klos/anaconda/lib/python3.6/smtplib.py", line 854, in  sendmail
    msg = _fix_eols(msg).encode('ascii')
UnicodeEncodeError: 'ascii' codec can't encode character '\u0142' in position 111: ordinal not in range(128)

回溯（最近一次呼叫最后一次）：
文件“sendduemailremementer.py”，第57行，在
sendmailStatus=smtpObj.sendmail（'xxx@xxx.com",电邮,正文)
sendmail中的文件“/Users/klos/anaconda/lib/python3.6/smtplib.py”，第854行
msg=\u fix\u eols（msg）.encode（'ascii'）
UnicodeEncodeError:“ascii”编解码器无法对位置111中的字符“\u0142”进行编码：序号不在范围内（128）

如果有任何帮助，我将不胜感激。
