Elika,

Maybe this reply is not perfectly on topic... but anyways...

While developing a test [1] on text-shadow, I stumbled on the difficulty 
of figuring out where the emphasis marks for 'text-emphasis-position' 
should be respectively for glyphs with 'text-orientation: upgright' and 
'text-orientation: sideways'.

The spec on text-emphasis-position [2] states

   'over'
     Draw marks over the text in horizontal writing mode.

   'right'
     Draw marks to the right of the text in vertical writing mode.

but what if I use 'text-orientation: upright' on a run of text? Then 
what?

In this test

http://www.gtalbot.org/BrowserBugsSection/CSS3TextDecoration/text-emphasis-style-filled-circle-0xy.html

the middle stripe has 'text-orientation: upright' .
