Acrobat won't copy text

When I try to copy the text of a pdf file, it pastes as gibberish in other programs - does anyone know how to fix this?

A goggle search on ‘Acrobat won’t copy text’ hitting ‘I feel lucky’ gave me this…

Online conversion tools at Adobe:

They let you mail or upload a PDF and get text or html back.
In Adobe Reader you can use the button that looks like a T with a square to select text before copying and pasting. CTRL-a followed by CTRL-C usually works fine for me for what it is worth.

This can be disabled when the PDF document is created so that text cannot be copied and pasted.
