But I believe there is another problem: I'm pretty sure that the TrueType
rasterisation part of Win9x/Me does not support the newer cmap formats
that are required to display glyphs for non-BMP characters. So, the apps
may understand the characters, but unless they are reading the cmap tables
on their own and drawing text as glyph strings, you won't see the glyphs
on Win9x/Me.
I expect Chris was assuming Win2K/XP, since it is very definitely a better
platform for script support. This issue of support for newer cmap formats
is but one reason why.
