Why not? It is more compact for East Asia (apart from the fact that
compression can be used anyway). I might understand if you would say
that it might not be adopted by content providers. But for browsers,
supporting UCS2/UTF-16 in addition to UTF-8 is an extremely small
addition, so I don't even see why there is discussion about it.

It is not very harmful to label such pages ISO-8859-1 or whatever.
But strictly speaking, it is not legal! If there are alternatives
for labeling, the most restrictive label should be used. If it's
labeled us-ascii, you know that it's going to pass though 7-bit
mail. Otherwise, you don't.

I don't see that much of future popularity for purely NCR-coded
documents. These are more valuable for cases where you want to
add a character or two from a script not supported in the
local encoding used, e.g. a Kanji or two to a German document
or so.
