I've also gotten inconsistent results using various pdf to text 
converters[1], but getting an explanation for pdf2totext's failings here 
isn't likely to happen.  I'd first try google doc's on-line conversion 
tool to see if you get better results.  If you're lucky it'll do the job 
and you'll have confirmation that better tools exist.  Otherwise, I'd 
look for an alternate way of getting the bank info than working from the 
pdf statement.  At one site I've scripted firefox to access the bank's 
web based inquiry to retrieve the new activity overnight and use that to 
complete a daily bank reconciliation.

HTH,

Emile
