You are correct, Leonard - I ran my file through a PDF validator against all
the 5 or 6 variations of PDF (PDF/A1, PDF/A2 etc) and it failed every one - -
but so did all the other 30 or 40 different PDFs from all the other energy
suppliers! In fact every PDF document I have on my laptop fails to validate, so
it would appear on the basis of my (very basic) validation exercise that
nothing is ever 100% PDF compatible. I've even downloaded Abode Reader X
(10.1.2) from your company and looked at some of the PDFs supplied with that,
and they fail to validate ... Btw, Itext was happy to convert these other 30 to
40 PDFs to text, but not the one I posted ... I was just curious as to why

Just because Adobe Reader processes your file does NOT make it valid PDF.
Reader is EXTREMELY lenient because the average user would have no way to fix
such crappy PDFs. If you ran this file through the PDF validator in Acrobat, I
would bet it would fail. Leonard From: RIchard Hammond

trace wasn't posted because the problem is easily reproducable.
If you use Abode Acrobat Reader to view the PDF it looks fine as I tested this
before I posted the query. The original file was produced by a power company
(who should know what they are doing) Also, I have used another PDF to text
converter on the file, and that worked fine too ...
