HTML body to PDF with special characters "åäö"



I am trying to convert a HTML body to a PDF using HtmlFormatProvider and PdfFormatProvider. 

It works well when I try to create a pdf with "normal" characters, but when I use characters like "åäö" the characters is either missing or replaced with other character. 

I have found a similiar issue but that was due to the fact that the person was using .net core I am using .net framework. 

Am I missing something when I am converting it to a PDF or is there a limitation with special characters like "åäö". 


        private string CreateAndStorePdf(string htmlBody)
            Telerik.Windows.Documents.Extensibility.JpegImageConverterBase jpegImageConverter = new Telerik.Documents.ImageUtils.JpegImageConverter();
            Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.JpegImageConverter = jpegImageConverter;

            var provider = new HtmlFormatProvider();
            var document = provider.Import(htmlBody);
            var exportProvider = new PdfFormatProvider();
            var fixedExportProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Pdf.PdfFormatProvider();
            var fileName = "_original.pdf";

                using (var outputStream = new MemoryStream())
                    exportProvider.Export(fixedExportProvider.ExportToFixedDocument(document), outputStream);
                    outputStream.Seek(0, SeekOrigin.Begin);
                    var pdfBytes = new BinaryReader(outputStream).ReadBytes((int)outputStream.Length);

                    return fileName;
            catch (Exception ex)
                Log.Error(ex, "The pdf could not be created.");
                return null;

Hi Linus,

After the provided information in the forum, it appears that this is a known issue. So I'm going to decline this one. 

Here is the issue in this case: WordsProcessing: HtmlFormatProvider: Automatically detect the encoding instead of relying on the one set in the HTML.
