Miraz, thank you for the link. are you sure it is authentic? it appears to me it is written by hindus - very little mention of arab or persian or turkish influence! lots of mahabharat etc.
in pakistan we had alphabet for sindhi and punjabi similar to hindi like bengali, but we discarded it and went with modified arabic alphabet so that we are free of influence from the non-muslim neighbour.
is it easy to learn bengali? it sounds very sweet when i hear bengali brothers talk at the mosque. are there bengali movies?
