adobe reader - PDF has garbled text when copy pasting

I'm trying to copy and paste text from a PDF file.

However, whenever I paste the original text it is a huge mess of garbled characters. The text looks like the following (this is just one small extract):

4$/)5=$13! ,4&1*%-! )5'$! 1$2$)&,$40! 65))! .*5)1! -#$! )/'8*/8$03! 
(4/+$6&4;0!/'1!-&&)0!*0$1!.9!/,,)5%/-5&'!1$2$)&,$403!5'!+*%#!-#$! 
0/+$!6/9! -#/-! &,$4/-5'8! 090-$+! 1$2$)&,$40! .*5)1!1$25%$! 1452$40! 
/'1! &-#$4! 090-$+! 0&(-6/4$! %&+,&'$'-0! *0$1! .9! /,,)5%/-5&'! 
1$2$)&,$40!-&1/97!"#$!+5M!&(!,4&1*%-!)5'$!/'1!,4&1*%-!1$2$)&,$40!

)*+*+, C<88,?>8513AG<5A14, 

I've tried it in both Adobe and Foxit PDF readers. I did a 'Save as text' in Adobe Reader and the resultant text file is the same garbled text.

Any ideas how I can get this text out non-garbled? (Other than manual typing... there's a lot of text to extract.)
