I'm reading a PDF copy of Jerome H. Friedman's paper "Data Mining and Statistics: What's the Connection?" using Google Chrome and the Adobe Reader plugin.

It contains an amusing quote that I want to copy and paste to my blog.

I used the mouse to select the text of the quote and pressed CTRL + C to copy the text. The document looks like this:

When I paste the text into Notepad, Stack Overflow, or anywhere else, the product is Wingdings-like gibberish:

????????????????????????|?????????|????? ?????|??????????????????????????????????????????????????|?????????????? ??????????????P????? ?????????????????????P?|?????????|?????????????????????????????????????????????????????? ????????????Þ?????????????????????????????????|???|???????????????????????????

The text should instead look like this:

A difference between statisticians and computer scientists in this field seems to be that when a statistician has an idea he or she writes a paper; a computer scientist starts a company.

I had to type that text out manually. This is feasible for such a small quote, but how do I actually copy what I see?

Is it something unusual about the PDF, the browser, the plugin, or some combiniation of the three?
