Also, I saw that bug report about font encodings being mangled beyond recognition. What does that suggest? That the fonts are unusual and unable to be picked up? I have seen that statement on a number of 'pdftotext' websites but I'm not sure what they're trying to say unless it just comes down to some fonts being unusable by the utility. The font in this particular PDF does not seem to be unusual but I have no real reference.

I think we posted at the same time there. Yeah, asking the trading partner to conform to something is dicey to say the least. What I find unusual is that this structure has been in place for quite awhile and AFAIK, this is the first time that a PDF simply will not process using 'pdftotext'. That along with the size suggests that this particular PDF was created under unusual circumstances. What I need to do is tell my customer that this PDF is incompatible but I would like to tell them WHY so that the trading partner might be able to do something different. I dislike mysteries and I don't like to say that something doesn't work without understanding why. It's definitely mysterious. Thanks again for the help. I appreciate it.

       emb    "yes" if the font is embedded in the PDF file

       sub    "yes" if the font is a subset

       uni    "yes" if there is an explicit "ToUnicode" map in the PDF file (the absence of a ToUnicode map doesn't necessarily mean that the text
	      can't be converted to Unicode)

       object ID
	      the font dictionary object ID (number and generation)

       PDF files can contain the following types of fonts:
