# [OS X TeX] Problem with Quotes in PDF File

I sometimes create LaTeX files containing programming examples.  I
distribute these file to students electronically.  I would like them
to be able to copy the code in these files, paste them into a text
editor, and try them out.  Unfortunately, this doesn't work with the
PDF files I create with TeXShop.  I think this problem is not
specific to TeXShop or the Macintosh, so this may not be the proper
place to raise this issue.

Consider the following LaTeX file:

\documentclass{article}
\begin{document}

\begin{verbatim}
!"#$%&' ()*+,-./ 01234567 89:;<=>? @ABCDEFG HIJKLMNO PQRSTUVW XYZ[\]^_ abcdefg hijklmno pqrstuvw xyz{|}~ \end{verbatim} \end{document} This will produce an output file containing every printable ASCII character. Unfortunately, the left quote () and right quote (') are not the same in the output file. If I open the resulting PDF file in Acrobat Reader and copy the characters, I get !"#$%&’
()*+,-./
01234567
89:;<=>?
@ABCDEFG
HIJKLMNO
PQRSTUVW
XYZ[\]^_
‘abcdefg
hijklmno
pqrstuvw
xyz{|}~

There are two differences.  In the source file the left quote is
octal 047 (39 decimal, 0x27 hex).  In the PDF file the left quote is
0222 in octal (146 decimal, 0x92 hex).  It seems that the character
has been translated into its "curly" equivalent.  The same thing has
happened to the right quote.

Of course, compilers are unforgiving about something like this.
Students can't just copy code examples and expect them to compile
which is a big problem.

Is there any way to fix this?  That is, I would like the correct
values for left and right quotes to appear in my PDF file.  How can I
accomplish this?
