In general, you'll get better responses if you provide a minimal but  
complete example to show exactly what you're doing.

However, I think I can guess: I suspect that the font you're using (in  
the verbatim environment) was loaded via fontspec, probably with  
\setmonofont, and you specified the [tex-text] mapping, either in the  
\setmonofont declaration itself or with \defaultfontfeatures. If you  
want "---" to remain three separate hyphens, etc., then you *don't*  
want [tex-text], which replaces those sequences with single Unicode  
characters, to be applied to your monospaced font.

So remove that option from \setmonofont, or put your \setmonofont  
command before your \defaultfontfeatures.
