Using this file from the Copyright Office with Adobe Reader 9.3.1 on Mac 10.6.2 Snow Leopard:
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?
Now I have discovered that this happens when the pdf os downloaded using Chrome. but downloading using Safari the pdf seems fine.
