This method might fail to remove font bytes in the following cases:

property is false.
Font is used by one of form controls (PdfTextBox, PdfComboBox,
etc.) and therefore can't be unembedded. A PDF reader might be unable to view or change
text in a control if the control uses an unembedded font.
Font is a Type3 font. Type3 fonts cannot be unembedded by its nature.
Current document will be saved as a PDF/A document. For such documents
