single quotes in strings, example block

Dear R-devel,

In the example block of the documentation for a package, I need to use
a single quote in a string:

    foo <- "Don't know"

After building the package, it gets printed as:

    foo <- "Dont know"

I read the "Writing R Extensions" and "Parsing Rd files" from top to
bottom, but didn't find any solution.

Using \verb{} doesn't help, as:
Tag \verb is invalid in a \examples block

Neither \sQuote doesn't help, as:
'\s' is an unrecognized escape in character string starting ""Don\s"

I found the only macros which are interpreted within text are \var and
\link ... therefore I am stuck.

Any hint to other documentation I might read?
Thank you,
Adrian

I don't see this.  Can you give more details, i.e. R version, how you
printed it, etc.?

It may be that you're not using an ascii single quote character, your
editor has slipped in something else.

R.version

It must be related to my computer, then... it appears in the PDF file
created after the R CMD check.
It helps a lot, now that I know it is a possible MacOS matter, I will
re-post this in the R-SIG-MAC

Just in case, here are the details:

R.version

               _

arch           x86_64

Thank you,

Okay, now I see it in the PDF output of R CMD Rd2pdf on  MacOS.

This is an Inconsolata font issue.  If you look at the .tex file
(available with "R CMD Rd2pdf --no-clean") you'll see the quote there,
but LaTeX doesn't display it.

I don't remember what the fix is...
