[jira] [Resolved] (PDFBOX-4036) Invalid ToUnicode CMap in font
[ https://issues.apache.org/jira/browse/PDFBOX-4036?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oleksii Zinkovskyi resolved PDFBOX-4036.
----------------------------------------
Resolution: Not A Bug
Thank you for the quick response. A faulty file was my primary idea as well, but since working with this particular file is a major business requirement in my current project I wanted to be completely sure that the issue was the file itself and not something I was doing or the tools I was using. I believe you've addressed all of my concerns, thank you.

> In the end the file is generated and properly saved, but some letters are missing (like "ft" in "software" or "ff" in "different"). So far I've tested close to 10 files and this is the only problematic item I've found. Depending on what program I use to view the resulting .txt file, I either get blank spaces (Notepad) or "NUL" values (Notepad++) in place of the missing letters. What's more, some editors (Sublime Text Editor) outright refuse to open the file and view it as unreadable/corrupted byte code. Suffice to say working with such a file is somewhat difficult...
