I see the standard hyphen used as a dash by many writers.<br/><br/>Example: <br/><br/><span style="color:rgb(0,0,0);">We will fly to Paris in June - if I get a raise. </span><br/><br/><span style="color:rgb(0,0,0);">Smith offered a plan - it was unprecedented - to raise revenues.</span><br/><br/><span style="color:rgb(0,0,0);">Is it OK to do so?</span><br/><br/><span style="color:rgb(0,0,0);">Thanks.</span>
