The exception is thrown when CIDSet is imported.

I am using the trial version of telerik for xamarin for .net core which was released last year, to convert pdf to text. Our service is hosted in Azure. The text which I get back, in certain cases the spaces are missing (say for example instead of 'I [am] here', it displays 'I[am]here'. This happens randomly. 

The code which we have used is as follows -

byte[] pdfBinary = Convert.FromBase64String(inputString);

 TextFormatProviderSettings textFormatProviderSettings = new TextFormatProviderSettings("\r\n", " ");
         
 var textFormatProvider = new TextFormatProvider();
 var pdfFormatProvider = new PdfFormatProvider();

 RadFixedDocument document = pdfFormatProvider.Import(pdfBinary);
 result = textFormatProvider.Export(document, textFormatProviderSettings);

At this point, the import logic cannot automatically repair such documents and a NullReferenceException is thrown while reading them. You could repair the invalid file using the project from the attachment.

Implement Replace method(s) which enable the users to replace a concrete string/content/text in a PDF document (RadFixedDocument).

Workaround: 
Check the sample project attached ("RemoveText.zip") that demonstrates how to remove text separated into several text fragments.

A KeyNotFoundException is thrown when trying to open a PDF containing specific Type1 font.

Hello Telerik,

Last time we attempted this the <Viewbox> contents would not render and were empty upon xaml to pdf output. It would be great if you had this feature and we could move completely away from raster output to PDF for controls that contain Viewboxes. Otherwise we have really liked the PDF's created by the tool, the vector output is sharp as expected.

Thank you,

Patrick

Workaround:

Use PdfFormatProvider or reflection to register the char (check the comments).
