Currently the rotation applied to the Zhuyin Fuhao (注音符號) for all glyphs in vertical format follows the metrics for the font. But to support Zhuyin the four tonal marks-- 0x02ca, 0x02c7, 0x02cb, 0x02d9--need to be rotated the opposite direction from the other glyphs--so guess that means that absent a VERT table entry for the font(s) LibreOffice would have to handle. @Mark, Khaled -- is that something we can achieve per locale, similar to with bug 106295?
@V Stuart Foote - yes, that is technically feasible. However, I need further investigate to see if they are expected to be rotated occasionally.
Maybe you can try to use several combining diacritical marks as tonal marks, if you do so, what happened in vertical layout?
@Volga, VO property of Combining Diacritical Marks is still R. On the other hand, 0x02ca, 0x02c7, 0x02cb, 0x02d9 are the characters that I get directly from Microsoft IME. I think they are used for quite long time.
