it does not copy periods or apostrophes.
Strange! That's a bug for sure. Save your work as a UTF-8 text file and send it to firstname.lastname@example.org
so I can what's up. I may not have time to bugfix the early book kit until the final version is released, but I can at least help you identify the offending characters in the meantime.
Also, try submitting your book so I can see what kind of output you're getting. You can overrwrite earlier submissions so don't worry if it's not quite how you want it yet.
Also, there is no way for me to use my direction keys to situate the blinking line where you type.
That's a feature not a bug. It's not meant to be a full-featured text editor, just a place where you can paste existing text from an external editor like notepad or something - adding that kind of functionality would take time away from the game / other kits.
Language is to the mind more than light is to the eye.
