Hi. I think This is related to [this](https://discourse.processing.org/t/special-characters-problems-in-apde/13433) , a topic from @Eeyorelife I tried to answer.  
But when I write “println(s.length());” within mousePressed() I just get a string length of 1. I was expecting two characters because when I hit a backspace the letter will appear.
