Kazuaki,

With Firefox 43.0a1 buildID=20150815090753, TakaoPGothic font is used to 
display that Ｔ (decimal code is 65332) in your 
text-orientation-mixed-001 test.

With Firefox 40, NanumMyeongjo font is used to display that Ｔ (decimal 
code is 65332) in your text-orientation-mixed-001 test.

With Chrome 46.0.2478.0, "Droid Sans Fallback" font is used to display 
that Ｔ (decimal code is 65332) in your text-orientation-mixed-001 test.

Firefox 43 uses NanumMyeongjo font, which is a font system on my system, 
for that page while Chrome 46 again uses "Droid Sans Fallback".



I think one way to work around the font required to render that Ｔ 
(decimal code is 65332) character in your text-orientation-mixed-001 
test would be to declare it specifically, intentionally and deliberately 
for "Droid Sans Fallback" font, like this:

<div id="vertical"><span style="font-family: 'Droid Sans 
Fallback';">Ｔ</span>ext sample</div>

[I just tried this with Firefox 40 and Firefox 43 and it works 
perfectly.]

Then do the same kind of research for Windows 8+ and Mac OS X Intel 
10.10.x with Firefox, Chrome and Edge browsers.
