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

This is causing issues when exporting the document to PDF from WordsProcessing - the pdf library tries to create the font, but cannot find it due to a different casing. When importing HTML document, the font-family property is read with small letters. Later, when converting the string containing the value, it is changed to title case. This issue will be reproducible with each font containing a name with a letter with casing different than the one of the other letters (exc. first capital letter), for example: Microsoft JhengHei

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:
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;
}
