### Examples

Shows how to set the default font substitution rule.

```python
doc = aw.Document()
font_settings = aw.fonts.FontSettings()
doc.font_settings = font_settings
# Get the default substitution rule within FontSettings.
# This rule will substitute all missing fonts with "Times New Roman".
default_font_substitution_rule = font_settings.substitution_settings.default_font_substitution
self.assertTrue(default_font_substitution_rule.enabled)
self.assertEqual('Times New Roman', default_font_substitution_rule.default_font_name)
# Set the default font substitute to "Courier New".
default_font_substitution_rule.default_font_name = 'Courier New'
# Using a document builder, add some text in a font that we do not have to see the substitution take place,
# and then render the result in a PDF.
builder = aw.DocumentBuilder(doc=doc)
builder.font.name = 'Missing Font'
builder.writeln('Line written in a missing font, which will be substituted with Courier New.')
doc.save(file_name=ARTIFACTS_DIR + 'FontSettings.DefaultFontSubstitutionRule.pdf')
```
