Using the Virtual Keyboard

I want to know whether there is a namespace that can show lowercase 'a' on the website.
Example : I used Qt::Key_A, this will give me uppercase 'A'.
So is there any namespace that I can declare or code that I can write in order to make the output shows lowercase 'a'?

As the symbol, I also need to know the code or namespace
