[jira] [Comment Edited] (PDFBOX-3053) Text extraction fails with
type 3 fonts
[ https://issues.apache.org/jira/browse/PDFBOX-3053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14972705#comment-14972705 ]

The reason that it works with the PDFBOX-2959-reduced.pdf is that this one has the character codes in the PDF identical to the text. In the "new" file, the codes are hex 1, 2, 3, 4 etc and that is what is extracted. Encoding:
3053 file (is ignored):
{code}
/Differences [1 /space /A /n /a /d /u /l /t /s /h /o /g /e /m /r /c /y /p /i /slash /f /colon /w /b /j /v /comma /k /period]
{code}
2959 file (is 1:1):
{code}
/Differences [32 /space 69 /E /F 72 /H /I 78 /N /O 82 /R 84 /T /U]
{code}
