So, that means, If I launch qemu with -k pt-br on a host, I need to 
ensure the keyboard layout
must be pt-br as well onthathypervisorhost,Then when I connected to this 
vnc server(qemu)
throughvncviewer on mylaptop(us keyboard layout), I type shift + 6, I 
can get¨(diaeresis)
character, am I right?
