You are now talking about something different from what you were saying
earlier. The script behaviour problem you mentioned was
"You'll see that "some" browsers still do not correctly handle the
needed reordering of vowels before display..."
This was explicitly in relation to Indic scripts. And the software you
"... Internet Explorer (IE6 or even in latest beta of IE7 on Windows XP
with the latest patches installed, and with Office 2003 installed with
additional fonts and most up-to-date Uniscribe engine). And if you
copy/paste it from Internet Explorer to MS Office Word or Excel
documents, where Uniscribe is used, things don't go really better..."
Re-ordering of Indic vowels most certainly does work on the Indic
scripts that are supported on XP (which is most of them).
Last time I checked, UCAS doesn't have any re-ordering vowels. :-)
Myanmar and Oriya were not supported on XP.

Bengali and Malayalam are supported in XP SP2, and the left matras
display on the left.

We display Telugu vowels where they belong in relation to the typeface.
Some attach above, some go below and some go lower right.

Lao and Tibetan are not supported scripts on XP. Lao, Tibetan, Khmer,
Oriya, Sinhala, UCAS - all these will be supported on Vista.

Keep in mind an important difference between bugs and unsupported
functionality. It is explicitly not a requirement of conformance to
Unicode that software needs to be able to correctly display or interpret
characters from this or that script. If a particular product does not
support Oriya script, it is not a bug; it is simply not a feature of
that product. Nine years ago, there were barely any (if any at all)
applications that could display Unicode-encoded text. Things have come a
long way since then, but work is still in progress.

I won't debate that point. But I will correct inaccurate statements such
as your earlier one about IE not handling re-ordering Indic vowels.
