Viewing Hindi, Tamil, Bengali Websites with Your iPad/iPhone/iPod
Apple's mobile devices are in general still unable to correctly display Unicode Indic scripts like Hindi, Bengali, Tamil, and Tibetan. But it turns that the Opera Mini browser can solve that problem for web pages by turning the text into a graphic. To activate this feature, you have to type opera:config in the browser address window. A page of settings will then come up, and you go to the very bottom one called "Use Bitmap Fonts for Complex Scripts", set that to Yes, and hit the Save button.
