Things have moved on a little since those referenced instructions, which were about embedding actual font files inside each and every epub. You can now achieve the same result more easily by copying the font files, once only, to the PRST1.
There are different approaches:
- use Calibre features to convert your books to epub (even if they are already epub). This will edit the css inside each epub to reference the Arabic fonts you have copied to the PRST1.
- update your PRST1 with Morkl's customised version of the Sony reading app. This will allow you to replace 1-6 fonts in the T1 select-a-font option (Menu - Font - Select Font Type) with fonts of your choice. Or if ALL your books are in Arabic you can configure the app so that 'Original' will be set to Arabic. No special editing of each epub is required. However, updating part of the Sony firmware cannot be considered 100% risk free. You'll probably be OK, but there are no guarantees.
- fully root your PRST1 (also not risk-free). You can then load other Android apps which have better font-handling features. Many people have chosen to do this but I'm not one of them. There are many threads about it in the MR Sony Reader Dev Corner forum.
First you need to decide which of the above you're most comfortable with. Then it will be easier to guide you on what to do next.
For further info, how many font files (.ttf) do you have? Is it just a single, trado.ttf, or are there also bold/italic variations. Please forgive my total ignorance of the finer points of Arabic
