			# Objective - Have a default font ## Solution - Add a font based on FiraMono containing only ASCII characters and use it as the default font - It is behind a feature `default_font` enabled by default - I also updated examples to use it, but not UI examples to still show how to use a custom font --- ## Changelog * If you display text without using the default handle provided by `TextStyle`, the text will be displayed
