If Bangla (form of Bengali?) is an LTR language (which I believe it is), it is supported. However, you need to add a font yourself as you have found out.
There are several topics here on mobileread about adding fonts. In general it comes down to adding the font to the ePUB and add references to it in the stylesheet. In the stylesheet you need to add an @font-face and in your elements a reference to the font-familiy.
For iBooks you need to add a 'com.apple.ibooks.display-options.xml' file to the ePUB.
Liz Castro also has a blog where she places info every now and then. There are also topics about fonts there.
