The Bengalis have dropped the letter "ৱ". Their “ক্ষ“ is a different issue on which Unicode have been told umpteen times by many, for Assamese it is a letter and for Bengalis it is a combination or conjunct.
See <http://www.unicode.org/faq/char_combmark.html#11>, and related FAQs. Before asking for “improvements”, you should be familiar with the pertinent FAQ collection, at the very least. Sincerely, Otto Stolz
