[BUG REPORT] Code generation messes up some UTF characters in user code sections

[Kazimierz Król]

I am using some UTF-8 characters in my code that shows messages to the user, and some of them get converted to some other code page when I regenerate the code. This happens when generating code both from CubeIDE ioc editor and CubeMX.

This is how my code looks before generation:

And after generation:

 

The characters �?, Ę and Ń get messed up.

CubeIDE version: 1.11.0

CubeMX version: 6.7.0

Hello Kazimierz Król,

Thank you for reporting this issue !

The C standard depends on the compiler and how it copes with the various character sets.

In gcc, you should be able to override the default (UTF-8) encoding using the -fexec-charset switch

Invocation (The C Preprocessor) (gnu.org). 

You might be able to use ASCII or some of the charsets listed here libiconv - GNU Project - Free Software Foundation (FSF).

Regards,

Rim

Thank you for the suggestions. I have already used other character encodings, but for this project I want to use UTF-8 specifically. CubeMX should not interfere with that.
