Issue with PDF Generation - Strange Symbols Appearing

Hello GemBox Support,

I am experiencing an issue when generating a PDF file using your library. The generated PDF contains strange symbols that do not appear in the original text.

Here are the details of my issue:

  1. Original Text Format: The original text contains HTML tags and is in French.
  2. PDF Generation Process: I am using GemBox to convert this text into a PDF file.
  3. Issue: In the generated PDF, the text appears with strange symbols. This issue occurs consistently when I generate the PDF.

Could you please advise on what might be causing this issue and how I can resolve it? Any help would be greatly appreciated.

Thank you, Raafat

Hi Raafar,

Those are ZERO WIDTH JOINER [ZWJ] characters (U+200D), they are written after a few <span> elements.

Anyway, try using this:

var document = new DocumentModel();
string html = @"<h2>La berce du Caucase</h2>...";
html = html.Replace("\u200D", string.Empty);
document.Content.LoadText(html, LoadOptions.HtmlDefault);

Does this solve your issue?


Hi Mario,

Yes, it works well using
html.Replace("\u200D", string.Empty);

Thanks a lot
