I decided to try this out since I love the idea of an eBook reader. I had a text file and dropped it onto ebook.exe and it spit a file two out (TITLE_OF_eBOOK.lua and TITLE_OF_eBOOK.tns). I transfered that .tns file but I was unable to open it.
Ugghhh!!
So I came back to this thread and read what the author said about text files that contain Unicode characters. I did a google search but did not find a quick way of removing the Unicode characters so I was stuck. I kind of gave up on it. Then I decided to open my original text file up using Notepad++
I discovered a great thing about Notepad++. It has the ability to convert text files to ANSI.
To do that just open your original text file up, prior to converting it using the ebook software, in Notepad++. Then choose:
"Encoding, Convert to ANSI".
Save that converted text file and convert it using the ebook software and BOOM!!! You have a file that you can use on the Nspire.
