I got directed to this and am puzzled.

I doubt it's any slower than before, apart from loading un-define.
What's the evidence?  The only relevant patches in Debian 0.84-11,
which appears to be the current package version, are one of mine and
one of Toby Speight's which probably slows decoding if anything.
(It's unfortunate for various reasons that the origin of patches
doesn't get recorded.)

I don't know what that refers to.  I explained the problem on
emacs-devel (I think) when it was first raised, as well as when I
posted the patch.  I made the bug fix that avoided Mule-UCS-induced
lossage.  You could have more success with the loading speed by not
defining any of the coding systems you don't use.  If that's not good
enough, handa had a suggestion for a different change to
`register-char-codings', but I seem to remember it was somewhat
incompatible.

If there's another problem that someone can explain, I might be able
to do something about it.  (himi isn't responding currently.)
Otherwise, perhaps it's just a case of things working better without
my name on. :-/.

Non-CJK users would probably do better for simply editing Unicode to
use the ucs-tables.el and modified utf-8.el I advertised recently.
CJK users could contribute to improving its CJK support, but that
requires the CCL patch to the Emacs core.
