Aspose.PDF find Windows and PDF Standard fonts in the system to use while generating the PDF documents. Otherwise, it selects the most suitable font that supports the used language characters. For the fonts which has license limitations, you can use below property to prevent the warning or exception:

Document.setDisableFontLicenseVerifications(true);

Furthermore, you can also use font substitution method to check which font was substituted:

document.FontSubstitution.add(new Document.FontSubstitutionHandler() {
            public void invoke(Font font, Font newFont) {
                System.out.println("WARNING: Font " + font.getFontName() + " was substituted with another font -> " + newFont
                        .getFontName());
            }
        });
