This is the first time, that I ever used PyQt5 and it's pretty good as well, so I built a text editor like thing with it, and I want to replace every typed character with another character in a QtPlainTextEdit. Actually what I want to do is something like what this website does: lexilogos.com/keyboard/sinhala.htm
Here in this website, they have a simple textarea and when we type, it just replaces every english character with a sinhala character, and of course in a meaningful way. So I need to do the same thing with python-qt5.
My code:

self.result.setPlainText(_printed_)

I think in order to achieve this, I need to constantly listen to all the characters typed in and first get the copy of previous characters to a variable and replace current characters and join them together or is there any other way? I don't know how to do it this way with these widgets and all.
