python-3.x - 如何在openCV中获取˚

Question

我想在图像中写˚(度数字符)。我正在使用Python和OpenCV。
但是，该字符显示为??。这是我的代码:

import numpy as np
import cv2
import matplotlib.pyplot as plt

read=np.ones((500,500))
temp=100
read=cv2.putText(read,'{:>8.2f} ℃'.format(temp),(20,100), font, 2,(255,255,255),4,cv2.LINE_AA)
plt.imshow(read)

这是输出:

谢谢你，德格拉西亚多
OIL效果很好

    import numpy as np
    import cv2
    import matplotlib.pyplot as plt
    from PIL import Image, ImageFont, ImageDraw
    
    font_path = 'C:\Windows\Fonts\Arial.ttf'           
    font_size = 48                                      
    font = ImageFont.truetype(font_path, font_size)     
    
    read=np.ones((500,500))
    temp=100
    img=Image.fromarray(read)
    draw=ImageDraw.Draw(img)
    draw.text((0, 50),'{:>9.2f} ˚C'.format(temp), font=font, fill=255)
    read=np.array(img)
    plt.imshow(read)
