Summary: IE’s writing-mode:tb-rl (CJK-style vertical text layout) renders fullwidth characters rotated when it should not Product: Wine Version: 0.9.44. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P4 Component: wine-shell32 AssignedTo: wine-bugs@winehq.org ReportedBy: chortos@inbox.lv
Since version 5.5, IE supports the CSS property ‘writing-mode’. It enables vertical text layout, in which text flows from top to bottom and lines flow from right to left. Fullwidth characters (including all non-specially-halfwidth CJK) are to be rendered as usual (with their top pointing towards the absolute top of the box), while halfwidth characters are to be rotated by 90°. In Wine, on the other hand, all characters are rotated no matter what width they are.
Here is a closely related piece of text from MSDN (http://msdn2.microsoft.com/en-us/library/bb250415.aspx): ‘Operating system limitations prevent the correct display of East Asian characters in an upright orientation in some configurations. This limitation has been eliminated in Microsoft Windows® 2000, but Microsoft Windows NT® 4.0 and Windows 9x systems require a version of the operating system that has been localized for an East Asian language to ensure that these characters display correctly.’
