How can I print an onscreen bool value?

https://github.com/EpicGames/UnrealEngine/blob/a27ad66f0a075f3b74ef8f68a4b2b0da4882425e/Engine/Source/Runtime/Engine/Private/KismetStringLibrary.cpp#L65

FString UKismetStringLibrary::Conv_BoolToString(bool InBool)
{
	return InBool ? TEXT("true") : TEXT("false");	
}

So really does not matter. That function btw is a node for blueprint and it’s not used outside of it (at least GitHub don’t find any use of that function)
