Of course this is true; I did not mean to suggest that a 
Unicode-compliant font would have all Unicode characters!  (I, as a 
sometime font developer, have no interest in creating ~65,000 characters 
per font--actually, over a million now with the supplementary characters!)

What I meant, given the context of the messages, was: if a font is 
intended to support Bengali--as I believe fonts that Mike was attempting 
to use were--then it should have all the Bengali Unicode characters and 
one should not get those blank boxes if one tries to display a character 
from that range in a document.  If it doesn't have all the Unicode 
characters needed for a particular range, it's either a pre-Unicode font 
or a badly constructed one.  Change "Bengali" to whatever language you 
need to work in at the moment.
