I tried you test on a PC running Mobipocket Reader and found that it supported practically everything. I do not have a Kindle to test this with. Can you capture some pages and display what you see on the device? On the PC I would expect it would depend on the fonts you have loaded.
Is it true that 7E looks like an ndash rather than a ~?
Did you intend to leave out U+00AD from you list?
On a PC I get Greek, Armenian, Coptic, Hebrew, some but not all Arabic, Syriac, Thaana and NKo
All of the Canadian and beyond are poorly formatted.
Beginning at U+2580 the graphics characters are spotty but it is likely the font set.
