From what I can tell, gnome-terminal (and vte derivatives) displays the test pretty well, but fails to align RTL paragraphs to the right, as I have found in my tests.

However, it seems that urxvt doesn't find some scripts: the tibetan declaration of rights shows up as boxes. In xterm, they show up as blanks.

Alignment is great in rxvt, xterm, gnome-term, but Konsole somewhat fails in the math formulas, just like my web browser (FF 59). Strangely, most terminals fail the first "compact font overview" except Konsole.. Alacritty also has alignment issues and significant latency in loading the file.

pterm seems impeccable all around, and i suspect mlterm would also do the right thing, but i only have the older 3.5 Debian version on hand...

So yeah, I guess that, again, pterm/mlterm would win at displaying unicode here as well, and the test shows some flaws in urxvt/xterm rendering that my simpler tests did not clearly show (although I did find issues with xterm).
