CSS Writing Modes Level 3

The biggest issue is the default text-orientation of common symbols and punctuation, so here's a table to start figuring it all out. :)

Orientation Code	Meaning
U	always upright
S	always sideways
G	upright with alt glyph, else fallback to sideways
?	unknown, please fill in
[1]	Special Behavior #1 (see notes below table)

Data Table

If a column has different behavior for Japanese and Chinese, then write both with a slash: Ja/Zh.
