[jira] [Closed] (PDFBOX-4026) Mathematical Symbols

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PDFBOX-4026?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tilman Hausherr closed PDFBOX-4026.
-----------------------------------
    Resolution: Not A Bug

Closing as there was no further reaction.

However I was able to find the file so I can tell why it doesn't work:
https://www.degruyter.com/downloadpdf/j/math.2017.15.issue-1/math-2017-0093/math-2017-0093.pdf
the math symbols can't be extracted because the font is incorrect. This can be seen with PDFDebugger, by looking at {{Root/Pages/Kids/\[0]/Kids/\[0]/Resources/Font/F46}}. Adobe can't get them either. You'll have to use OCR. I tested on the line "Let p be a prime number" near the bottom of the first page.
