Yes I can. And did not you notice that on all other architectures my
expectations are fullfilled?

Did it ever stop Unicode crowd from insisting that people should
better first prove usability of their new-characters proposals via
PUA? If one can expect stuff in the PUA work, why should not one
expect the stuff will still work when it is moved out of PUA?

Moreover, I expect more: for the simple-rendering Unicode ranges which
DO require knowledge about character’s behaviour, I expect that this
knowledge may be ADDED LATER without an OS upgrade. (Preferably even
without root access!) (At least what *I* develop supports this…)

This concerns at least the LTR/RTL flags, the line breaking flags, and
the combining status. (Is there anything else needed for
simple-rendering of text files?)

I'm puzzled: how this bears with your advocating upgrade to w8 for the
guy who liked to have Old Italic?

[Of course, the situation for this guy may be very different if he had
 a support contract with Microsoft [or whatever it is called]. If
 not, then I suspect the only difference w8 could bring would be that
 the problems he encounters “without” vs “with” w8 would get a
 “very-slim” vs “slim” chance to be looked at…]
