Description V Stuart Foote 2016-11-04 17:51:33 UTC
From bug 95836 attachment 121296 [details] renders with fallback CJK font. However the glyphs for punctuation--brackets and braces are not rotating. 

Steps to Reproduce:
1. enable OpenGL and new HarfBuzz based layout
2. open attachment 121296 [details]
3. observe the bracketing of the vertical text -- rotated

4. enable OpenGL and the old DirectWrite WinLayout
5. open attachment 121296 [details]
5. observe bracketing of the vertical text is correct.

Actual Results:  
glyphs for punctuation, using fallback font, do not rotate with the vertical text

Expected Results:
should rotate to match vertical layout as OpenGL with the "old" layout does.

Reproducible: Always

@Mark H., 

NEEDINFO to you, please change back to NEW when you provide details as to Windows and Graphics, the build of LibreOffice and if changing the font used in the document has any affect on the punctuation.

Also, is it just for fallback font usage as I've indicated--or is the punctuation not rotating when using fonts installed on your system?  Summary may need to be corrected.

I get the same result on Linux as well, and my guess it is related to https://github.com/behdad/harfbuzz/issues/355.

This looks to be resolved fixed. @Mark H. please verify it is correct for you now on system installed fonts.
