   Actually, you might have had hard time telling the display difference
depending on what characters you used for your testing EVEN IF you
configured browsers to use different (but with __very similar__ design
principles and look/feels) Unicode-cmapped (but NON-pan-script) fonts
for TC,SC, J and K *under MS Windows*.  This difficulty demonstrates
that CJK Unification in Unicode/10646 is not such a big problem as some
people tried to make it.
