Please consider making this reader compatible with Project Gutenberg (Plain Text UTF) files. I tried parsing out the bad characters (carriage returns), but I'm not sure how to get rid of them entirely. If that's too much, consider having a mode to ignore bad characters and not display them at all. Fantastic work regardless.

Apparently, Windows, Mac, and Unix all use a different type of carriage return and this is looking for the Unix one. In order to convert your books, you can use Notepad++ and double-click where it says Windows (CR LF) on the bottom right to change it to Unix (LF), or if you're using the basic Notepad, you'll have to open a txt file that's already formatted with the Unix type (check the PlayBook zip file) and paste the contents of your book there.
