Hi, thank you for having access to this report.

Here is STM32CubeProgrammer's output text.

This works fine, but he doesn't feel very well.

And I tried to use utf-8 encoding format, but it's still garbled.

Hi，Aziz

I've seen a lot Chinese users met that garbled character problem in other forums. Cause Vscode terminal is UTF8 by default and encoding 850 or 437 is rarely used in Asia. I change my local STM32VSCODE extension file, adding chcp 437 &&(or chcp 850 &&) right before STM32CubeProgrammerCLI command in "flash" task template, and that just fix mine. To get a better performance in more computers, is it feasible to add that "chcp 437" or "chcp 850" to extension's source code?

Thanks in advance!

This has nothing to do with VSCODE, the problem is on Windows Terminal. As mentioned earlier, I changed the code page to 850 before using the STM32ProgrammerCLI. Today I tried to active code page to 437, but the result is still the same.
