DescriptionFix default text orientation that do not conform Unicode Technical Report #50
This patch fixes the default orientation of glyphs in vertical flow.
In vertical flow, when the author does not specify the orientation of
glyphs using the text-orientation property[1], the spec defines[2] that
UA must typeset by following UTR#50[3].
Currently, Blink honors UTR#50 only for non-CJK code points, and some of
the non-CJK have incorrect orientation, resulting 462 failures in total.
This patch fixes both some CJK characters that must rotate, and
incorrect orientation of non-CJK characters.
Mongolian/Phags-Pa specific orientation test was removed as these
scripts are now covered by imported CSS WG tests.
One code point in the imported tests still fail:
text-orientation-script-001e.html
This needs further analysis, which is deferred from this patch.
