The Arduino IDE is based on a java application called processing. While typing text into processing, it refuses to accept any of the characters under dead keys like " ' ^. As a work around I:
- Open another window (usually my browser or mail client);
- I type the character I need;
- Select and copy the character onto my clip board;
- Copy the character into processing.
What do I have to do to make processing accept characters under dead keys? Disabling dead keys is not an option.
