Myles,

I do not get the last 4 glyphs (2 thin horizontal stripe and 2 thin 
vertical stripe) in this test page:

http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/Ahem2016TestPage.html

and I tried that test page with a browsershot web service and all the 
glyphs, except the last 4, were rendered on a non-Linux os.

What am I missing here? What is wrong with that test page?

The

http://www.gtalbot.org/BrowserBugsSection/CSS3WritingModes/support/ahem.ttf

filesize is 13884bytes, so it is the correct, newest version of the ahem 
font.

[Addendum: this page
https://www.w3.org/Style/CSS/Test/Fonts/Ahem/
makes no mention of the 4 glyphs! It seems that the font I got from
https://www.w3.org/Style/CSS/Test/Fonts/Ahem/
never was updated with the latest Ahem font version.
The
https://www.w3.org/Style/CSS/Test/Fonts/Ahem/
needs to be updated with the latest version of the Ahem font.]
