I want to convert a book I wrote to .epub format in order to display it in iPhones, iPads and Android using reading apps.
I already tried converting the file using Scrivener (Which worked on iPhones but not on iPads and androids) and with Calibre which has a bug with Hebrew letters.
A friend told me InDesign might be a good choice so I wanted to ask you:
 Is it possible to convert to .epub and display Hebrew letters in RTL direction and right text-alignment?
 If so, Which of the two programs should I purchase (199$ / 299$)?
 Does the convertion process is simple enough?
 Is it possible to convert to .mobi as well?
There are some difficult issues in what you're trying to do. One is that in order to get RTL support with InDesign, you need to be using InDesign ME. See a recent thread where I suggested the poster contact the company that produces the ME version for Adobe:
Second, you'll need to make sure the Hebrew font is licensed for embedding, and you'll need to learn about creating EPUBs in InDesign. I'd suggest starting with eBooks by Liz Castro.
