But how do we handle cases like 
dash + Bengali Vowelsign E + Consonant ?

The Bengali Vowelsign E is rendered before the consonant, and so, 

dash + Bengali Vowelsign E + Consonant

and 

dash + Consonant + Bengali Vowelsign E

will be same visually (last two lines at http://www.peacefulaction.org/

Somehow, we need to let the users know that method 1 is not the proper
"consonant ekaar[1]". People using the traditional ugly hack "Bengali
Software" are accustomed to hitting the key for ekaar before typing in
the consonant, and we need to be cautious about that.
