Issues with keyboard on SM-G950F

Hello guys,
i have an issue with my Samsung SM-G950F.
When i want to write message through scrcpy, i can't write uppercase with shift. I can use capslock, but it's a big problem when i'm writing messages.
When i'll use shift, i have littlecase.

Also i have an issue with latin characters like ą, ę, ć, ó, ł etc.
When i'll write ć and ó, i have something like this:

In consola i find these errors:
[server] WARN: Could not inject char u+0105 [server] WARN: Could not inject char u+0119

For any text problem, first try with scrcpy --prefer-text.

Only few non-ASCII characters can be emulated: https://blog.rom1v.com/2018/03/introducing-scrcpy/#handle-accented-characters
