Hi, Enjoy unicode supported Bengali website with your mobile that support Operamini. No need to download any thing, just need to configure your Operamini. To let you know how to do that I'd like to share my blog post [0] about it. But the blog is in Bengali, so you need do necessary configuration at you computer too to watch the blog. Let me know if you don't have the configuration to watch Bengali at you computer. I'll help you to have it too.
Again enjoy Bengali at your closest devices.
Cheers, Belayet
