It seems that Bangla Unicode fonts has two versions. Arial Unicode MS and Vrinda/Sagar has different appearance. What is kaa + aekar is not appropriate for Arial, it is the correct form of Avro.The two scripts have different juktakshshors too. Ajker Kagoj and Prothom Alo uses the Arial Family, while wikipedia uses Avro family. Is it possible to make a converter so that we could use data typed in Arial in Wikipedia?
