Hi Mark,

This is a curious PDF. This file has made created or manipulated with
PitStop application. This PDF have internally all the text totally and
highly altered. I will explain this complex structure and the reasons
for this strange character behaviour:

A. When you open the document with the Acrobat viewer, you will see all
characters with the same font style. Internally it's not the same. It
18 different font types (see the menu File > Document Info > Fonts)

B. Every font have an 'strange' and 'different' font encoding. In this
simple PDF there are 18 different font encodings (font encoding is the
correspondence with the 'character name' and this ascii code). For
example: in the particular font called 'FMNBBE+F19726528.0' the
character '9' have
the ascii code '1', when the standard ascii code for this is '57'

C. Also all the characters have their internal name altered. For
example: in the same font called 'FMNBBE+F19726528.0' the character '9'
the name 'c57', when the standard character name is 'nine'

D. By this reasons you will see well the text document only in the
Acrobat viewer, but when you 'copy and paste' the characters, you only
'transport' the 'rare and particular' characters codes, and the
disaster appears in the wordprocessor.

Have you tried to use a plug_in to extract the PDF text ? Do you know
if they extracts only strange characters ?

If you can't resolve the problem and you are interested on find
a tool to extract correctly the text, lets me know, and I can
develope it in a few days.

I hope this can help you.
