Not as far as I'm concerned.  The filters are freely available.  I
only have to actually type the filter pipeline once, after that I make
a shell function.

Sure, but all that matters is (1) chunking characters in the buffer
and (2) converting to integers for font indexing, both operations are
trivial and efficient.  This is very different if you want to handle
all of EUC and Shift JIS and ISO-2022-JP.  In Shift JIS you can't even
handle all Japanese characters; EUC is the best of the three and
reasonably consistent but what if you want to write Hangul or Hrvtska
(Croatian); and ISO-2022-JP means you don't even know where characters
begin and end without going all the way the back to the beginning.

Why burden a stupid little *term with that complexity?

I mean it should be easy to put filters on it so as to handle
arbitrary external representations.  These filters can be internal as
with Mule coding systems or Python codecs, or external such as piping
through iconv.  All knowledge of non-Unicode coding should be severely
limited to a few modules.

It should be like a Japanese house.  You may wear sandals, shoes,
sneakers, or boots outside, but when you enter the house you take off
your outdoor shoes and put on slippers.  In the same way, at the time
text enters a program, it should be converted into a universal
representation, ie, Unicode.  It doesn't matter whether the getabako
is inside the program (as the genkan in most homes) or outside (as at
my daughter's school).
