Fix ç (cedilha) on Ubuntu and its variants when using EN keyboard layout.
Alternatively, you can press "alt gr" + "," (alt graphic, the one on the right side, and comma) on your keyboard to use the cedilla without having to run this script.
Usage:
git clone https://github.com/silveira/cedilha.sh.git
cd cedilha.sh
chmod +x cedilha.sh
sudo ./cedilha.sh
