Yes, its assumed that some browsers alow this to be configured. That
other browsers do not allow it to be easily/at all configured does not
invalidate the concept.

Yes and no. Its hard from a simple setting to set different preferences
for different languages (it is possible in a user stylesheet, although
by language not by script). Also, recall that the generic font families
are not the  end of the chain - just the end of expressed preferences. A
browser can, and should, attempt to display a character that is not
displayable using a specified or generic font by using any other font it
knows about.

Well, if its the users preferred language then they would presumably set
one of those fonts as their default.

AC> Just my 2 cents worth.
