The imread function for reading images and the imshow function for setting image titles should support Chinese characters

[loli0123456789]

Expected behaviour

The functions imread for reading images and imshow for setting image titles can support Chinese characters

Actual behaviour

1.When using the imread function to read an image with a path that includes Chinese characters, the function returns None. 2.When using the imshow function to display an image with a Chinese title set, the displayed title appears as corrupted text.

After reviewing the relevant documentation, I remain unclear on how to resolve the issue.

Steps to reproduce

• example code

`import cv2

def read_img(img_path): img = cv2.imread(img_path) return img

def show_img(img,title): cv2.imshow(title,img) cv2.waitKey()

img=read_img(r'D:\测试\lenna.png') print(img) # the result is None

img=read_img(r'D:\Test\lenna.png') show_img(img,'测试')`

Issue submission checklist

• [ ] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)

• [ ] I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)

• [ ] The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")

• [x] I'm using the latest version of opencv-python
