ArrayIndexOutOfBoundsException in Type1CharString
[ https://issues.apache.org/jira/browse/PDFBOX-2487?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14701744#comment-14701744 ]

--------------------------------------------------------------
This was an interesting bug, I'd got one of the stack depth checks off-by-one, which would usually result in totally malformed charstring rendering. However, the bug occurred on the "seac" operator, which build composite characters, so it had the effect of completely eliminating the rendering of these.
