My point, which I guess I did not get across, was that the normative names
for the unified CJK characters are completely uninformative : the information
content that I can extract from "U+4E00" as the code point value and from
"CJK UNIFIED IDEOGRAPH-4E00" is the basically the same -- the only difference
being that the normative name tells me it is a CJK character. But which one?
I recognize *why* it was done this way and I was not, nor am I now, going to
argue about the normative CJK naming. I was merely trying to point out that
there is precedent for having different rules for different blocks in Unicode,
with CJK unified ideographs and Hangul syllables being examples.
If the Unicode Consortium had accidently mixed up the names of letters
in the Latin alphabet, say like this:
A LATIN CAPITAL LETTER B
B LATIN CAPITAL LETTER A
C LATIN CAPITAL LETTER D
D LATIN CAPITAL LETTER C
... and then *insisted* that these names were immutable, would the consortium
not be the laughing stock of the ISO, W3C, IEC, IETF, and numerous other standards organizations?
Would the ISO and IEC really have allowed such a thing to stand when it came
time to ratify the standard?
But for Lao ... ooops, it will have to stand uncorrected. Obviously the
government of the Lao People's Democratic Republic is not a member of the
