title: Can I use en/em dash in markdown?
body: <p>I am writing a technical manual using git. </p>
  
  <p>Is there any problem caused if I use en or em dash such as <code>&amp;#8212;</code>?</p>
  
  <p>(For example) Voltage: 5&#8211;12 V</p>
  
  <p>Some people say, when this special character is rendered from Markdown to HTML, the rendered character might be broken in some websites.</p>
