That's OK.  This assumption is not important.  You can do the decoding in
the process filter, or anywhere else.

There can be several buffers.  Remember in point 1 I said "temp buffer".
And I'm sue it can be all done within a multibyte buffer if necessary.

You can run a CCL program independently from any coding system.
