PdfProcessing: Newly created SignatureDataProperties object misses Contents initialization
Sign a random pdf document with the following code. If UseSignatureProperties=1, the produced PDF document will be corrupted and Adobe displays an error message when opening the file: 
        Dim signProp As New SignatureDataProperties
        signProp.ContactInfo = strContactInfo
        signProp.Name = strSignersName
        signProp.Reason = strReason
        signProp.Location = strLocation
        signProp.TimeOfSigning = DateTime.Now

        Dim signatureName As String = "EsignSignature"

        Dim signatureField1 As SignatureField = New SignatureField(signatureName)
        UseSignatureProperties = 1

        If UseSignatureProperties = 1 Then
            Dim sign1 = New Signature(certificate)
            signatureField1.Signature = sign1
            signatureField1.Signature.Properties = signProp 'THIS WOULD FAIL
        Else
            signatureField1.Signature = New Signature(certificate)
            signatureField1.Signature.Properties.ContactInfo = strContactInfo
            signatureField1.Signature.Properties.Location = strLocation
            signatureField1.Signature.Properties.Name = strSignersName
            signatureField1.Signature.Properties.Reason = strReason
            signatureField1.Signature.Properties.TimeOfSigning = DateTime.Now  'THIS WORKS
        End If

PdfProcessing: Fonts are not merged when merging documents
When merging documents using the RadFixedDocument`s Merge() method the fonts are not successfully merged which leads to missing characters in the produced document.

Workaround: replace the font with a full font (not a subset) before exporting to a PDF file:
byte[] data = File.ReadAllBytes("verdana.ttf");
FontFamily verdanaRegularFontFamily = new FontFamily("Verdana");
FontsRepository.RegisterFont(verdanaRegularFontFamily, FontStyles.Normal, FontWeights.Normal, data);
FontsRepository.TryCreateFont(verdanaRegularFontFamily, out FontBase verdanaRegularFont);

foreach (RadFixedPage page in mergedDocument.Pages)
{
	foreach (TextFragment textFragment in page.Content.Where(c => c is TextFragment).Cast<TextFragment>())
	{
		textFragment.Font = verdanaRegularFont;
	}
}
