However, all of this isn't really necessary, because all current Kindles (K3 and higher) support RTL text (some older Kindle apps don't).
If you use Calibre to generate Kindle files, select AZW3 and not MOBI as the target format. You can also simply open your source file with Kindle Previewer
, which will automatically generate a master mobi file.
Some time ago, I created an Arabic/Hebrew font embedding test file that you can use to test whether your Kindle supports KF8/AZW3. (The source code is embedded.)
