title: ansi to unicode conversion
body: <p>While parsing certain documents, I get the character code 146, which is actually an ANSI number. While writing the char to text file, nothing is shown. If we write the char as Unicode number- 8217, the character is displayed fine.</p>
  
  <p>Can anyone give me advice on how to convert the ANSI number 146 to Unicode 8217 in C#.</p>
