I apologize for my idiosyncracies affecting others. I was disappointed that by default most installations (a) turn of rendering of Indic scripts so that you see ????? rather than squiggles you don't understand :-), and (b) People's spam filters discriminate against all non-English senders instead of only Korean and Chinese :-), so I started using my name in Bengali.
Since this is not the lounge, let me bring it on topic by referring to http://www.behindthename.com/bb/arcview.php?id=193774&board=gen
where I explained my name (actually http://www.behindthename.com/bb/arcview.php?id=171626&board=gen
is also relevant) . My posting name is my real name: sig of either message gives my real homepage (and the index of my genealogy linked from there explains all names that occur in my genealogy: so I am back on topic, somewhat)
