[jira] [Closed] (PDFBOX-729) Disable text extraction whne using
type3 fonts (was: Text extracted from a TeX-created PDF file is
unintelligible, but not of the form a1a2a3...)
[ https://issues.apache.org/jira/browse/PDFBOX-729?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Hewson closed PDFBOX-729.
------------------------------
Resolution: Won't Fix
On the other hand, some Type 3 fonts do contain useful text, which is why Acrobat attempts to extract text from them. This is a good call, and PDFBox should continue to do the same thing.

> Text extracted from some PDF files is completely unintelligible, presumably depending on the software used to create the file. In this example, a combination of dvips(k) 5.95a Copyright 2005 Radical Eye Software (to create PostScript) and Acrobat Distiller 8.1.0 (Windows) (to create the PDF file) was used. The text extracted looks like
> CFCTCXCTD6D7D8D6CPH3B9C1D2D7D8CXD8D9D8
> CUH0D6 BTD2CVCTDBCPD2CSD8CT BTD2CPD0DDD7CXD7 D9D2CS CBD8D3CRCWCPD7D8CXCZ
> CXD1 BYD3D6D7CRCWD9D2CVD7DACTD6CQD9D2CS BUCTD6D0CXD2 CTBACEBA
> C
> Only rarely some bits and pieces of recognisable formulas are interspersed.
> The text copied using either Acrobat Reader or Preview looks different, but is similarly unintelligible.
