```

Specifies the reason of font substitution.

 **Examples:** 

Shows how to get additional information about font substitution.

```

 Document doc = new Document(getMyDir() + "Rendering.docx");

 WarningInfoCollection callback = new WarningInfoCollection();
 doc.setWarningCallback(callback);

 FontSettings fontSettings = new FontSettings();
 fontSettings.getSubstitutionSettings().getDefaultFontSubstitution().setDefaultFontName("Arial");
 fontSettings.setFontsFolder(getFontsDir(), false);
 fontSettings.getSubstitutionSettings().getTableSubstitution().addSubstitutes("Arial", "Arvo", "Slab");

 doc.setFontSettings(fontSettings);
 doc.save(getArtifactsDir() + "FontSettings.SubstitutionWarnings.pdf");

 FontSubstitutionWarningInfo warningInfo = (FontSubstitutionWarningInfo)callback.get(0);
 Assert.assertEquals(WarningSource.LAYOUT, warningInfo.getSource());
 Assert.assertEquals(WarningType.FONT_SUBSTITUTION, warningInfo.getWarningType());
 Assert.assertEquals(FontSubstitutionReason.TABLE_SUBSTITUTION_RULE, warningInfo.getReason());
 Assert.assertEquals("Font \'Arial\' has not been found. Using \'Arvo\' font instead. Reason: table substitution.", warningInfo.getDescription());
 Assert.assertTrue(warningInfo.getRequestedBold());
 Assert.assertFalse(warningInfo.getRequestedItalic());
