How to show CJK characters in button label or window title?

[thelastfantasy]

Hello I'm learning gtk4-rs with https://gtk-rs.org/gtk4-rs/stable/latest/book/hello_world.html
I changed the label to include some Chinese characters in the sample code but got this error message.

I think there would be some problems with the encoding but I don't know how to solve it.
Would anyone please help me?

Rust source files need to be UTF-8 but it looks from the error message like you added the Chinese characters in a different encoding. Can you check that?

Thank you for your reply!
I think it's because I forgot to close the "my-gtk-app.exe" instance.
my-gtk-app.exe file can be launched from explorer after cargo build now.

But another problem is, my-gtk-app.exe executable file can only run from explorer (double click), when I tried to run it with cargo run I always got this error↓

error: process didn't exit successfully: target\debug\my-gtk-app.exe (exit code: 0xc0000139, STATUS_ENTRYPOINT_NOT_FOUND)

Maybe I need to create a build.rs file?

You need to make sure that all required DLLs are in the PATH when running the application, as always on Windows. You can use https://github.com/lucasg/Dependencies to list all dependencies of your executable and to get an idea which ones are not found.
