I've just edited the First_Look example of the PdfViewer. If I generate a text export, by using:
var provider = new PdfFormatProvider(str, FormatProviderSettings.ReadOnDemand);
RadFixedDocument doc = provider.Import();
textBlock.Text = new TextFormatProvider().Export(doc, new TextFormatProviderSettings());
I recognize, that the results are not as expected. Some special characters are not correctly translated. In figure 1 the special character ‘ (\u2018) is displayed in the pdfview correctly whereas in the generated text the character was translated in \u0091 which is for private use. Also for non special characters there is also an unexpected behavior visible. In figure 2 it is visible that the 'fl' is missing in the word 'beeinflussen'. The string is translated in "beein\u001fussen". This means that the two characters 'fl' is replaced by the single character \u001f. This \u001f means 'Unit Seperator' which makes in this context not much sense for me.
Thank you
