Copy and paste from PDF in Preview results in gibberish

Thoughts?

10.5 is not going to be fixed, but hopefully as a result of the bug report mentioned in this thread there might be a fix in a future version of 10.6.

I have the same problem with this file:

http://www.copyright.gov/orphan/comments/OW0642-PPA.pdf

and was able to resolve it using the Adobe online pdf converter

although it lost a bit of the formatting

Using this file from the Copyright Office with Adobe Reader 9.3.1 on Mac 10.6.2 Snow Leopard:
http://www.copyright.gov/title17/circ92.pdf
I can only copy and paste some of the text. Other text turns to odd characters when used in the find box or copied to a Mac app.

This text on the cover: "Copyright Law of the United States" , comes out empty boxes like this:
The words also don't show up in a search.If I copy the text to Microsoft Word it shows the same boxes but identifies the font as "TheMixExtraBold-Plain"
Document Properties>Fonts shows that font as (Embedded Subset) Type:Type 1 (CID) Encoding: Identity-H

However with the text above it "c i r c u l a r 9 2" I can search and cut and paste fine. That text is "Minion-RegularSC" and Document Properties>Fonts shows that font as (Embedded Subset) Type:Type 1 Encoding: Roman

Oddly, when printing the page both fonts show up fine.The same problem occurs in Mac Preview.
Document Properties>Description says the file was created by Adobe InDesign CS2 (4.0.4)

How can I copy paste and search this document?

this is posted in pieces because the forum cannot handle comments of more than a sentence or two and gives a fake error to boot " We're sorry, Apple Discussions is temporarily unavailable. We'll be back soon. Until then, please visit http://www.apple.com/support" #APPLEFAIL.

How can I copy paste and search this document?

Maybe you can't. There are various different ways of encoding text in pdf's and some of them make copy/paste and searching impossible.
