Sorry that I didn't make it clear: what I meant is that the examples
of having conflicting mapping are mostly HK centric.

Let me sort it out the argument:
based on data collected from dotnetdotcom.org, you find that
big5-hkscs gives best mapping to unicode. (microsoft maps all the user
extension area of big5 to private user area, PAU, of unicode ) So you
suggest to merge the big5-hkscs to big5 as IE supports big5 only.

But I tried to point out is that big5-hkscs uses reserved extension
area in big5 which may conflict with other big5 variants like
big5-uao. As you pointed out the difference between big5 and
big5-hkscs in Firefox, that exactly the difference as Firefox adopted
big5-uao, which covers the most big5 variants used in Taiwan.

Also, from my understanding (sorry I use linux and I don't know HK
dialect at all), HK people used to have to apply a patch to read/write
HK dialect characters under windows. (including conversion table,
input method and extended font 細明體_HKSCS) Please refer to wikipedia

With the patch available here:
HK people's "big5" under windows will be effectively "big5-hkscs",
though still name it as "big5". So they won't have problem with IE
which supports "big5" only. (it's a patched "big5")

According to wikipedia, HK official stops the support of big5-hkscs.
All the exchanging document should use ISO 10646 (unicode) From
microsoft: http://www.microsoft.com/download/en/details.aspx?DisplayLang=en&id=12080
there will be no support starting windows vista, either.

If one installed a big5-uao patch (community made) for windows, he/she
can view those contents under all software utilize the system
conversion table under windows. But Firefox uses its own conversion
table so the big5-uao merge is needed. AFAIK, those big5 variants are
covered by the 細明體 "MingLiu" system font under windows, so no special
font needed. This is not the same case for HK extension as those
glyphs were not in unicode yet at that time.

For HK related contents, it's either you specify "big5-hkscs" in
Firefox/Chrome/Opera encoding, or install the patch from HK government
to view in IE. I don't see the need of merging big5 and big5-hkscs.
Also from your survey, big5-hkscs works best for HK related contents.
To me, having two major big5 variants, big5-uao and big5-hkscs, is the
best solution.

There are many college BBS system, which still using big5 instead of
unicode, providing web interface, not just ptt.cc. Just that I
personally didn't touch them for long.

I really don't know. PieTTY and PCMan bbs software also has UAO
builtin. Can I count all people using Firefox and PCMan?
