Friends using the Astra Theme might find that the theme loads an Astra.woff font by default when optimizing website speed. This Astra.woff is a font that comes default with the theme and contains some commonly used icons. As shown below:
This font is used in the following places:
The search button at the end of the top-right menu, the dropdown icon of the menu, and the mobile menu button.
So under normal circumstances, we cannot disable this font file.
If you really don't use this font, you can disable it with the following command.
Add the following code to the functions file
add_filter( 'astra_enable_default_fonts', '__return_false' );
