title: File input of avformat_open_input in ffmpeg
body: <p>I'm trying to use function <code>avformat_open_input</code> in <em>FFmpeg</em> to open the file which contains Chinese word.</p>
  
  <p>For example: </p>
  
  <pre><code>char* file="C:/測試/baby.mp4";
  
  avformat_open_input(&amp;pFormatCtx, file, NULL, NULL);
  </code></pre>
  
  <p>But, it seems to be failed.</p>
  
  <p>My question is how do I pass the file path which contains Chinese (or other languages except for English) ?</p>
