I agree. And, I've never claimed that all unifications done by
Unicode are incorrect. Most of them are ok, I think.

Again, I didn't claim all of them were failure. But, there surely
exist many failures. How can you claim that all of them are not

I agree, but there surely exist some boundary between acceptable
variants and incorrect ones. For most Japanese, I believe, the
example of `choku' is the case that unification has done too much.

No. Most writers want that a character he enters and sees on his
display is displayed/printed with one of acceptable variants of glyphs
on a readers display/printer. In the case of hand written text, a
writer knows that a reader sees exactly what he writes, and it's his
responsibility to write a readable glyph. In the case of electric
communication, it's the responsibility of a character set.

Could you give some example?
Anyway, I believe the example of `choku' is the case of failure in any
standard of Japanese. And, as far as Unicode doesn't admit that it is
a failure, the same failure may occure in the future. This is the
bigger problem than just the fact that the current Unicode contains a

Hmm, you come to the key point of unification problem. Please ask any
Japanese if he think it's a bug of something (not knowing exactly
which of display handler, font, input method, or the character set
itself) or not if he sees Chinese glyph when he enters `choku' by some
Japanese input method?
I claimed in many places (but perhaps not in this mailing list) that
unification of two characters in two different cultures has potential
difficulty especially in the case of ideograms. If culture A want
characters X and Y be unified but not with Z, and culture B want X and
Z be unified but not with Y, what kind of unification is good? I
think the character X (Y and Z also) for culture A and X for culture B
are different characters even if they have exactly the same glyph.

Then, why they wanted to put different code points on them? Which is
better for computer environment to keep "1" and "l" the same code
point or not? Your example is the example that characters should not
be unified just by the reason that they look similar and in most cases
there's no readability problem.
