title: Print Unicode Characters to POS printer
body: <p>I'm trying to print my language characters to a POS printer. The Printer prints well but the result's so bad. This is what I tried:</p>
  
  <pre><code>using (MemoryStream ms = new MemoryStream())
                  using (BinaryWriter bw = new BinaryWriter(ms))
                  {
                      bw.Write(AsciiControlChars.Escape);
                      bw.Write('@');
  
                      //ESCCMD.RenderBitmap(bw, logo);
                      bw.Write("Đây là Tiếng Việt");
  
                      bw.Write(AsciiControlChars.Escape);
                      bw.Write('d');
                      bw.Write((byte)3);
  
                      // Feed 3 vertical motion units and cut the paper with a 1 point uncut
                      bw.Write(AsciiControlChars.GroupSeparator);
                      bw.Write(AsciiControlChars.V);
                      bw.Write((byte)66);
                      bw.Write((byte)3);
                      bw.Flush();
  
                      RawPrinterHelper.SendToSerialPort(ms.ToArray(), txtPortTest.Text, Convert.ToInt32(cbbBaudRate.SelectedValue));
                  }
  </code></pre>
  
  <p>So how can I print my language characters using ESC/POS command? 
  Thanks so much!</p>
