sample odt file

Some glyph (Mongolian, English) orientation are incorrect on Mac on vertical text direction mode. I create an illustration to explain it.
Selection highlighted area is not fit to glyph boundary.

Thank you for your bug report.

why is this bug tagged as "regression" without any indication that it has ever worked in a previous release?  it even has "Inherited from OOo" as version, indicating it's a bug that is many years old.

also if it's happening on Mac only it's probably a bug in VCL not Writer.
Comment 7 Khaled Hosny 2014-11-27 19:57:14 UTC
I don’t think this ever worked in Mac, at least that the impression I got last time I checked the VCL code in Mac since it did not implement any of the stuff the “unx” VCL implements for glyph orientation in vertical layout (which itself needs an overhaul, but that is a different story).

I very want to have this bug fixed soon.
I found a way to make glyphs orientation of Mongolian correct. 
This way will make English glyph  rotated in vertical layout, I know this is not expected for people who are native English. But this is the definitely correct way to show English on vertical layout for me.
The problem I could not solve is that the text protrude from their bounding rect.
