[jira] [Comment Edited] (PDFBOX-4064) cm operator has 7 numbers
[ https://issues.apache.org/jira/browse/PDFBOX-4064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16324294#comment-16324294 ]

That's a bug we've seen in other google-produced PDF documents. It happens here because of a difference in parsing in the "outer" part of PDF file and in the content stream. In the first, the "\-" is passed to the {{COSFloat}} constructor, in the second, it isn't, i.e. it considers the "\-" to be part of the next token. Because of that, {{PDFDebugger}} shows these 7 parameters. I tried being more lenient but it produced regressions so more investigation is needed.
