There is a discussion about how the Sony displays Gutenberg TXT files here:
https://www.mobileread.com/forums/showthread.php?t=15780. In particular, see post #12 by Kacir. Note how the Sony displays the file as-is, with all the line breaks in the original text file.
This brings up a good question. How does the Cybook handle this? Does it have any additional smarts about displaying text files like the Gutenberg ones, or does it do like the Sony and display them as-is?
I have attached the Gutenberg text of Grimms Fairy Tales, which is what Kacir used. Would someone with a Cybook please try this and let us know how it looks, using the same part of the text? A picture would be really nice, if you could manage it.
