[second posting - first one got lost?]
As part of the TrueType font signature up to 128 bits are set to mark the
unicode ranges covered by the font.
What is the latest assignment ?
As far as I know it goes up to bit 83, with bits 8, 12, 14, 27, 58, 84-127
reserved.
What about the higher planes ? Are no bits set to cover this ?
Apparently the Unicode consortium is not concerned with this, and one has
to go the Microsoft site to see how the bits are assigned.
I have used these sites :
For the ranges:
http://www.unicode.org/Public/UNIDATA/blocks.txt,
for the bits:
http://www.microsoft.com/typography/OTSpec/OS2.htm.
The tail end of the listing, as far as I can fix it, is as follows :
