This looks good. (I get CM Roman instead of LM Roman with your
example but this should not have any influence on - and *.)

I tested again with your example as well as the printable characters from
Unicode Blocks Basic Latin and Latin-1 Supplement. The result when copying
back into text is:
x−y
and
30 ! ” # $ % & ’
40 ( ) * + , − . / 0 1

So I expect this to be a problem of your PDF Viewer or clipboard or OS.
Could you try with another viewer?
With Postscript instead of PDF?
On a different computer?
Send the PDF as pm?

OK this points to an encoding issue.

In the "evince" PDF viewer, there is a menu entry "Properties" with a tab
"Fonts". Something similar should be possible with other viewers, too.

This looks not good: besides the "-", also "*" is mapped to "?".
And non-ASCII is even worse.
Is this with non-TeX fonts or with TeX fonts?
Which output format?

Re: insert listing so it can be copy/pasted from pdf
Guenter and Joel
I appreciate your help but I am coming to the conclusion that the pdf file
format is not well enough defined to be able to reliably embed software
listings that the reader can copy/paste into a file and then be able to compile
the results. I will have to continue as I have done in the past to include a
listing in the pdf but also to provide a link to a supplementary online zip
file with the source code in text files.

p.s.
Guenter, here are the answers to some of the questions in your response:
>Does it show up as hyphen or as question mark in the PDF?
It is displayed as a '-' in the pdf but copy and paste of the 3 characters in
the listing results in x?y with '?' being 3F hex according to my editor.
>Which fonts does your PDF use?
I do not know how to answer that question. How do I find out what fonts it uses?
>What is the result if your listing contains: ...
Here is what I get if I enter your list into the listing, create a pdf then
copy and paste the text in the listing.

Does it show up as hyphen or as question mark in the PDF?
Which fonts does your PDF use?
Maybe it is a lookalike character in the source?
Which character code do you get when copying from the LyX-GUI?
Are there similar problems with other characters in listings?
What is the result if your listing contains:

Here, I was able to save the example from my text editor to a file, open it
in LyX and compile:
Drag-and-drop from the PDF results in:
x−y
With the - beeing the ASCII Character (45, 0x2D) 002D HYPHEN-MINUS
