Changing default font of Arabic/Persian text in Kindle 3 WIFI

[wlaf]

Last year, with 3.4 update for Kindle 3 WIFI, at last we could be able to create Arabic/Persian mobi/epub files and see them correctly on the device:

Arabic/Persian text on Kindle 3

But there is another problem. Default font, called code2000 is so ugly that can not be called 'usable'. Because of this, I tried several methods for changing the default font, but with no success:

1. Embedding Fonts: Using embedded fonts in documents does not have effect on Arabic/Persian text and only changes font of the English text.

2. Remapping Fonts: Using alternative (alt) font with Calibre "Kindle Collections" has the same result and has no effect on Arabic/Persian text.
It seems that Changing the mapping file didn't work for Arabic/Persian, and that is the reason this method does not work.

Here is some more description from Doitsu:

Once a font hack is available you'll probably be able to remap it to another font. AFAIK, It's possible to remap fonts on K3 without a jailbreak, but I don't know whether the same method works for a PW.
You may want to ask in the Kindle developer forum if it's possible to remap code2000.ttf to a better font without a jailbreak.

And even with a font hack it might be tricky, because the Arabic glyphs come from the code2000.ttf fallback font. I.e. you could probably only replace the default font with one other Arabic font of your choice.

but I'm curious about the solutions:

1. Changing the Code2000 font: Reading the description on Wikipedia, I come across the point that code2000 has a very large range of writing systems, that may be lost with replacing it by a simple font that support few languages.

2. Editing Code2000 font: It seems a better way, but it is hard to implement. Every single character should be modified in a font-editing program, and with different scales between fonts and considering the complex script and needed joining of them, may be porting some fonts' glyphs to work with Code2000 is not an easy task.

I would be happy to hear suggestions from you.

As Doitsu said, the Fonts Hack can override code2000 (I18N), if I remember the tests we did correctly.
