I've installed over 159 new fonts, all that were possible in Gentoo mirror.

Answer 1

According to http://www.fileformat.info/info/unicode/char/10100/fontsupport.htm the following several fonts support U+10100: Code2001, EversonMono (and EversonMono Oblique), MPH 2B Damase, and Penuturesu. Note that Code2001 isn’t where it used to be, but it can be downloaded from my Code2001 page. And you can add ALPHA-Demo and Quivira to the list.

Fileformat.info shows no support for U+1EE00, and I don’t know of any font that has it. The font used in the Unicode chart for the block is Uni1EE00Arabicmathsymbols (according to Adobe Reader), but I can’t find any info on it.

The situation looks similar for Avestan, Bamum, Brahmi – no support so far, in publicly available fonts.
