adobe acrobat export character capitalization and spacing issue

I am trying to export a pdf document in acrrobat pro and when I try doing it in HTML, xml, etc the capitalization and spacing of words are all wrong.  Yet, it shows correctly on the page.

FOR Example.  a TITLE:
Self-Limiting Growth of Metal Oxide Thin Films Using Pulsed PECVD

Exports as
Self-limiting Growth of Metal oxide thin films using Pulsed PeCVd

Even just a simple copy and paste into a text editor from the document does the same thing.  

Also words get clumped together.  

for example:  I like to run over to the river and sit.

ends up being:

Iliketorunover to the river and sit.
I've got about 1000 documents that I need to parse text out so i'm trying to get these in some kind of format so that I can parse the text.  

Can someone advise why this is doing this and if there is anything I can do to resolve it


FYI The meta data is unusable as it only has part of the text that I actually need.  Looking in the document properties the application is Adobe InDesign CS2.

I've attached the XMP data of the doc in case that gives any idea as to the issues.

Unfortunately you are out of luck: In order to extract textual information from a PDF, the PDF needs to contain a "ToUnicode" mapping table that allows the extractor to take a glyph code (which references the character that's drawn on the PDF page) and maps it back to a real character in your extracted text. That table is corrupt in your PDF document.
Your best chance to extract all the data is to use an OCR program (e.g. Abbyy's FineReader) to recover that information.
