Converting RTF with Superscript Two Character Adds Junk Character to PDF


I have an RTF file that looks like this (simplified from the original):

{\rtf1\ansi\ansicpg1252 1234567890²}

Just in case the forum messes up the characters, the last character before the closing curly brace is the “Superscript Two” characters, U+00B2 in Unicode. It’s the literal superscript two character, not a regular two formatted as superscript.

I use Aspose.Words to convert the RTF to PDF. It gives me a PDF that looks like this:


Note character in between the zero and the superscript two. It’s U+00C2, Latin Capital Letter A With Circumflex.

Here is the C# code I use:

string rtf = “{\rtf1\ansi\ansicpg1252 1234567890²}”;

byte[] rtfBytes = Encoding.UTF8.GetBytes(rtf);

using(var inStream = new MemoryStream(rtfBytes))
var loadOptions = new Aspose.Words.LoadOptions();

loadOptions.LoadFormat = LoadFormat.Rtf;

var document = new Aspose.Words.Document(inStream, loadOptions);

var saveOptions = (Aspose.Words.Saving.PdfSaveOptions)Aspose.Words.Saving.SaveOptions.CreateSaveOptions(SaveFormat.Pdf);

using(var outStream = new MemoryStream())
document.Save(outStream, saveOptions);

byte[] result = outStream.ToArray();

return result;


Hi Tom,

Thanks for replying!

The RTF attachment was the same was what I posted in the text: {\rtf1\ansi\ansicpg1252 1234567890²}. I cannot attached the original RTF having the problem since it has patient sensitive information in it. I’ve attached the sample again in a ZIP file.

Thanks for creating the support issue!
