I have an issue with PdfStandardsConverter, some Arabic are not properly translated from the original PDF.
I have an existing license and using spire.pdf for NET, version 10.1 and using VS 2015 version.
Please see attached file for your reference.
this is the code that i used;
Dim outputfile As String = "C:\outfile.pdf"
Dim inputfile As String = "C:\input.pdf"
Dim newDOC As Spire.Pdf.Conversion.PdfStandardsConverter = New PdfStandardsConverter(inputfile)
newDOC.ToPdfA3A(outputfile)
