we found that some PDFs aren't parseable by pdftotext function,
creating documents completely full of garbage.
It's not a permission problem (pdf blocked in copy&paste), more probably
is an encoding problem : opening them with acrobat/xpfd, i can see
character fonts with enconding type "embedded".
Did somebody find this type of pdf files ? Anybody resolved ?
We can find them simply with this select :
select *,length(word) fron eprint__rindex where length(word) > 35
In attach a screenshot with some of the eprint__rindex records garbaged ...
With this select you'll find also pdfs using high unicode characters : a
world will open you :-D
