Imshow incorrect title if non ascii characters

まず、提供された Python スニペットと opencv-python 4.5.5.62 を使って、報告された Windows 10 X86 のケースを再現してください。最初にリポジトリの README と build-toolchain の対象範囲を確認してください。payload にはファイルもテストのエントリーポイントも含まれておらず、報告された imshow の動作はこの packaging リポジトリではなく OpenCV に属する可能性があります。

Expected behaviour

I put a title on imshow like 'Données du ministère de la santé' and I expect to show it

Actual behaviour

The title show is 'Données du ministère de la santé'

Steps to reproduce

• example code

from cv2 import imshow, waitKey, destroyAllWindows, imread

from PIL import Image, ImageDraw, ImageFont
filename = "tmp.png"
fnt = ImageFont.truetype('arial.ttf', 20)
image = Image.new(mode = "RGB", size = (400,40), color = "blue")
draw = ImageDraw.Draw(image)
draw.text((10,10), "Données du ministère de la santé", font=fnt, fill=(255,0,0))
image.save(filename)
image  = imread(filename)
imshow("Données du ministère de la santé", image)
if waitKey(0) == ord('q'):
   destroyAllWindows()

• operating system
  - windows 10
• architecture (e.g. x86)
  - X86
• opencv-python version
  • 4.5.5.62

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")
• I'm using the latest version of opencv-python
