[ https://issues.apache.org/jira/browse/TIKA-911?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tyler Palsulich updated TIKA-911:
---------------------------------
Affects Version/s: (was: 1.1)
1.8
> Converted PDF document contains question marks in place of spaces and inconsistent case
> ---------------------------------------------------------------------------------------
>
> Key: TIKA-911
> URL: https://issues.apache.org/jira/browse/TIKA-911
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 1.8
> Reporter: Matt Sheppard
> Attachments: Rust Biosecurity Brochure.pdf, Rust Biosecurity Brochure.pdf.html
>
>
> The PDF document at http://www.grdc.com.au/uploads/documents/Rust%20Biosecurity%20Brochure.pdf, when converted with tika v1.1 using
> {code}
> $ java -jar tika-app-1.1.jar Rust\ Biosecurity\ Brochure.pdf
> {code}
> Produces substantially worse output than xpdf's pdftotext program.
> Specifically, we see...
> Some 'spaces' replaced with question marks
> {noformat}
> ...
> <body><div class="page"><p/>
> <p>How can I help?
> When you're overseas:
> • ?wherever?possible,?don't?visit?crops?—?contact?with?
> </p>
> <p>growing?crops?greatly?increases?the?risk?of?contaminating?
> footwear?or?clothing;?
> ...
> {noformat}
> and some odd case conversions
> {noformat}
> <p>stem rust in wheat.
> (soURce: BRAd collIs)</p>
> <p/>
> </div>
> {noformat}
> (The original document seems to contain "SOURCE: BRAD COLLIS" all in upper case.
> To compare that with pdftotext
> {code}
> $ ./xpdfbin-linux-3.03/bin32/pdftotext -enc UTF-8 -q ~/Rust\ Biosecurity\ Brochure.pdf
> {code}
> This does not output the question marks, and produces "Source: BRAD COLLIS" at the end there, both of which seem to be improvements. Note that it does, however, produce a number of ^G characters which are not desireable.
