How to reset "dead key state" -> Accents like ^ ` ´ which await another key to form ÂÊÎ...?

When pressing the keys for accents like ^ ` ´ on the keyboard it awaits another key to form letters like ÂÊÎÔ…
When now binding a key lets say to open and focus a textfield widget like a chat, we would want to write into it immediately, which when writing vocals results in Â, Ê, É, … Which breaks the workflow! It seems to be quite difficult to reset the state of this, since i assume it is part of the operating system and outside of UE!
I tried clearing the fslateapplication focus, and i set the focus to textfield anyway (keyboard focus)
Chatgpt knows no further and so do i, right now i manually correct the input text to not have these accents but this seems very inefficient

Thanks already and happy new year
