It looks like OSX's CoreText does funny things when vertical mode is requested for fonts that don't understand the concept of vertical mode. I suggest to experiment with the pCFVertBool variable in main/vcl/aqua/source/gdi/ctfonts.cxx or by disabling the line setting the value for KCTVerticalFormsAttributeName altogether. If it shows that only fonts without OpenType's "vert" or "vrt2" feature are affected then we could add a check for this and then work around the CoreText problem.
