Gets or sets the password required to open a PDF document as a string.

The two properties UserPassword and UserPasswordBytes allow to define the password as a string or as an array of bytes.

According to the PDF specification, a string password should be converted to an array of bytes using the system code page (if the standard security handler with revision 4 or less is used). In some environments the system code page is unavailable, so GcPdf cannot perform this conversion. If the password string only contains ASCII chars, this does not present a problem. But if the password string contains non-ASCII Unicode characters, it is up to the developer to perform the conversion and set the password using UserPasswordBytes.
