title: What is the difference between EM Dash #151; and #8212;?
body: <p>I've an ASCII file that contains an EM Dash (— or <code>&amp;mdash;</code> in HTML). The hex value is 0x97. When we pass this file through one application it arrives as UTF-8, and it converts the character to 0xC297, which is <code>&amp;#151;</code> in HTML. However, when we pass this file through a different application it converts the character to 0xE28094 or <code>&amp;#8212;</code>.</p>
  
  <p>What would cause these applications to convert these characters differently? Is it perhaps a code page setting?</p>
