This sample shows how to handle PDF-specific exceptions thrown by Docotic.Pdf library in C# and VB.NET.
Besides standard .NET exceptions (such as ArgumentNullException or ArgumentOutOfRangeException) the library throws exceptions of the PdfException type and its subtypes. These exceptions are specific to PDF format.
The library throws them when you try to do something that is not allowed or invalid from the PDF standard point of view. This sample shows one of such situations: a try to draw some text with characters which are not supported by the current font.
