I have a problem with my Arduino IDE, I am currently using the 1.6.4 IDE (on an XUbuntu 14.04 machine regularly updated), but this problem existed before the upgrade. I feel I have seen a solution somewhere before, but searches over the last few months have turned up nothing that helps. The problem lies in the layout font with the IDE menus and prompts etc
As you will notice the name of the file and menu prompts have rectangles replacing characters.
I am quite happy with the fonts that I use to do the editing and I know how to change them, but I really need help to tidy this annoying problem up. I suspect ‘Java’ but I have no idea where to start on that can of worms. Anyone?
