title: Special characters on file path:. Slash symbol
body: <p>I work with files. And use code like this:</p>
  
  <pre><code> PdfWriter.GetInstance(newFile, new FileStream(WebConfigurationManager.AppSettings["StorageFolder"] + "\\" + DateTime.Now.Year.ToString() + "\\fnp\\request_" + myVariable+ "_l" + confirmLevel.ToString() + ".pdf", System.IO.FileMode.Create));
  </code></pre>
  
  <p>This line generates my file's full path. For example, if <code>myVariable="0001"</code> then it is OK. So newFile's full path will be something like, say, StorageFolder\2016\fnp\request_0001_l2.pdf.  But I want to assign myVariable value  like <code>myVariable = "0001/16"</code>. Then <strong>PdfWriter.GetInstance</strong>  method tries to create path like StorageFolder\2016\fnp\request_0001\16_l2.pdf. But I need it to create StorageFolder\2016\fnp\request_0001/16_l2.pdf. </p>
  
  <p>How can I manage it? </p>
