[jira] [Comment Edited] (PDFBOX-1648) FontBox can't load CMaps with
no spaces between tokens
[ https://issues.apache.org/jira/browse/PDFBOX-1648?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14157965#comment-14157965 ]

----------------------------------------------------------------
This looks like a similar case to PDFBOX-2035, which further highlights that the CMap parser was only using whitespace as delimiters in some cases where in fact the full range of allowed PDF delimiter characters should be used.
I have updated the patch to the latest 1.8.8-SNAPSHOT and will attach it in the hope it may make it to the src, and we can stop patching every release we upgrade to.

> Issue Type: Improvement
> Components: FontBox
> Affects Versions: 1.7.0, 1.8.2

> FontBox (tested versions 1.7.0 and 1.8.2) can't load CMap entries if they're not properly separated by whitespace making it problematic to extract the text from such PDFs. Test case and a proposed patch attached. The patch is tiny but in case it matters: it is in public domain, no credit necessary, please feel free to relicence it as you see fit.
