title: What are the limitations for bookmark names in Microsoft Word?
body: <p>I need to bookmark parts of a document from the name of paragraphs but the name of a paragraph is not always a valid name for a bookmark name. I have not found on Google or MSDN an exhaustive list of limitations for bookmark names. </p>
  
  <p>What special characters are forbidden? </p>
  
  <p>The only thing I found is that the length must not exceed 40 characters.</p>
