Using utf-8 as input/output encoding.
Well I can't hard code classes or spans when ever letter changes.
The font I'm using (have to use) is a custom (@font-face) utf-8 font and includes all Arabic & English charcters, the English/Latin ones displays poorly, not as bold as the Arabic there for I need to use a better suited font for the English letters as I CAN'T replace the Arabic font I'm using.
Another solution of course is to edit the font from the ground and redesign the English letters.
The solution I'm looking for should be some thing that doesn't effect the page load time, as it's priority #1 for the project.
The solution doesn't need to be only CSS depended.
