           Summary: Wrong rendering of 16-01.ps
           Product: Ghostscript
           Version: HEAD
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Text
        AssignedTo: ken.sharp at artifex.com
        ReportedBy: alex.cherepanov at artifex.com

Test file 16-01.ps is rendered incorrectly by all versions of gs but there
are significant differences between versions.
v. 7.20 and earlier
  correctly uses eofill on the self-intersecting path but applies
  eofill to the contours that should be drawn separately,
  position of "~197" is correct.
v.7.21 to 8.71 uses fill on the self-intersecting path. The effect 
  on different contours is masked.
  position of "~197" is correct.
v.9.00 and later is similar to 8.71 but position of "~197" is incorrect.

PDF file generated by v. 900 and HEAD looks correct in Acrobat.
v. 9.00 and HEAD strokes all characters instead of filling,
position of "~197" is correct.
HEAD with the upcoming CFF patch renders PDF file similar to v.8.71
with correct position of "~197".
