Google’s Translate service now added support for the iPhone, when visiting the site from an iPhone or iPod Touch you will have access to a version of the site optimized for the iPhone/iPod Touch interface. The Arabic however is not as it is supposed to be.
Since the iPhone/iPod Touch 2.0.1 lacks Arabic support the Arabic letters will appear unconnected and useless. And the Google Translate page doesn’t even offer the option to switch the interface language. Macworld also noted this:
the iPhone still does not correctly display Arabic script (it displays letters individually, without the connecting ligatures, which effectively makes it gibberish). This isnâ€™t a fault of Google, of course; itâ€™s a problem with the iPhoneâ€™s version of Safari (similar problems had existed in the OS X version of Safari, but seem to have finally been ironed out).
But the current iPhone Arabic display problem is system wide. The iPhone currently have no Arabic support as of iPhone 2.0.1 software.
