Reference output by Adobe Acrobat.
To render the sample PostScript by Adobe Acrobat with WadaGo-Bold,
you should install WadaGo-Bold font file into the directory:
C:\Program Files\Adobe\Acrobat ?.?\Resource\CIDFont\
I'm assuming that mpsuzuki overlooked the default assignment to 'support' Created attachment 3736 [details]
PS file draw vertical text with CIDFontType0 including "nop"-like CDevProc
Modified sample file that inserts "nop"-like CDevProc to genuine CIDFontType 0
and tries to draw vertical texts.

Acrobat Distiller output of sample PS file #3736
Acrobat Distiller output of modified sample file #3736,
which inserts "nop"-like CDevProc to genuine CIDFontType0
and tries to draw vertical text. The text flows horizontally.

Patch to restrict unwanted CDevProc application
Igor's changeset SVN revision 5607 is the application of
CDevProc in any case. If I insert "nop"-like CDevProc to
genuine CIDFont dictionary aslike:
/HeiseiMin-W5 /CIDFont findresource
dup length 1 add dict copy
dup /CIDFontName /HeiseiMin-W5-Fix put
% just pop CID and keep metric infos as they are
dup /CDevProc { pop } put
dup /CIDFontName get exch /CIDFont defineresource
the PDF generated by Adobe Distiller shows text flowing horizontal.
It seems that this bug is "correct" behaviour when unwanted
CDevProc is applied. If I restrict the application of CDevProc
to the case CDevProc is explicitly defined, this bug (vertical
text flowing horizontally) is fixed.
