No. Did you see the image that I sent?

The character that shows in the mailer as '‹'  *is* 
actually an endash in some encoding.
It shows that way when looking inside the  .tex  file
that was attached.

As to why it changes to something else in the mailer
is one of those cosmic-ray like mysteries.
Perhaps we are seeing just 1 byte of a multibyte sequence?

In any case, this is a very good reason to *not* include
such characters directly into (La)TeX source.
You just cannot trust what will result when sending to
someone else, unless you use pure ASCII.
