> 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/>

> {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.
