Put unicode characters to signature widget
To put national characters to the widget text, you need to put the whole text in unicode and also to include a font, which will be used to display the widget, to the document.
Putting the text to the widget in .NET is trivial:
Sig.WidgetProps.SignerCaption = "My Unicode text"
Putting the text to the widget in VCL can be done as follows:
Sig.WidgetProps.SignerCaption := SBUtils.StringOfBytes(SBUtils.WideStrToUTF8('My Unicode text'))
To embed a font, see TinySigner sample, shipped with SecureBlackbox.
