Encoding issue (utf-8) of German umlauts on Windows

[dsvanidze]

I have encoding issues when I use German special letters in the Shiny app on Windows. It renders them incorrectly in a browser and also in the terminal output.

To reproduce, app/app.py file has just two lines of code:

from shiny.express import input, ui, render
print("üäöß")

When I run this code with Python python app/app.py, it prints the letters correctly. However, when I run the Shiny App with shiny run --reload --launch-browser app/app.py, it prints the following üäöß.

I just use print() here, but exactly the same happens with the string, when I use Shiny components to show text. This issue does not occur, when I run the app on WSL.

How can I fix the problem on Windows so that German text can be rendered correctly?

We recently merged a fix (#1203) for encoding issues on Windows.

Can you try installing the development version from github and see if it helps?

pip install https://github.com/posit-dev/py-shiny/tarball/main
