How to draw Chinese text on the image using `cv2.putText`correctly? (Python+OpenCV)

The cv2.putText don't support no-ascii char in my knowledge. Try to use PIL to draw NO-ASCII(such Chinese) on the image.

import numpy as np
from PIL import ImageFont, ImageDraw, Image
import cv2
import time

## Make canvas and set the color
img = np.zeros((200,400,3),np.uint8)
b,g,r,a = 0,255,0,0

## Use cv2.FONT_HERSHEY_XXX to write English.
text = time.strftime("%Y/%m/%d %H:%M:%S %Z", time.localtime()) 
cv2.putText(img,  text, (50,50), cv2.FONT_HERSHEY_SIMPLEX, 0.7, (b,g,r), 1, cv2.LINE_AA)


## Use simsum.ttc to write Chinese.
fontpath = "./simsun.ttc" # <== 这里是宋体路径 
font = ImageFont.truetype(fontpath, 32)
img_pil = Image.fromarray(img)
draw = ImageDraw.Draw(img_pil)
draw.text((50, 80),  "端午节就要到了。。。", font = font, fill = (b, g, r, a))
img = np.array(img_pil)

cv2.putText(img,  "--- by Silencer", (200,150), cv2.FONT_HERSHEY_SIMPLEX, 0.5, (b,g,r), 1, cv2.LINE_AA)


## Display 
cv2.imshow("res", img);cv2.waitKey();cv2.destroyAllWindows()
#cv2.imwrite("res.png", img)

Refer to my another answer:

Load TrueType Font to OpenCV

According to this opencv forum, putText is only able to support a small ascii subset of characters and does not support unicode characters which are other symboles like chinese and arabic characters.

However, you can try to use PIL instead and follow the answer posted here and see if it works out for you.
