The Unicode site already provides two repositories of HTML files showing
text in various scripts: the "What is Unicode?" pages and the "UDHR in
Unicode" pages. However, the former does not yet have an example in
Myanmar and the latter does not use font overrides (leaving it up to the
user's configuration), so the problem as stated is not yet fully
resolved for Myanmar.
I think creating "test pages... for all complex scripts" might be seen
as beyond the scope of the Unicode Consortium, especially to the extent
these pages are intended to test and compare browser and font
capabilities, and not just demonstrate correctly formatted Myanmar (or
whatever) text. Implementing Javascript and CSS so the user can change
fonts and sizes dynamically sounds like a task better suited to the W3C
or one of the many "how to build awesome internationalized Web apps"
sites.
I don't see how we go from my claim that the Ayar site is Unicode, but
might not be well-ordered, to Philippe's suggestion that the Consortium
should embark on this rather ambitious new project. Perhaps he is
volunteering.
