Hi there,
At this time, there’s no filter to change and allow the subset to be changed.
I just went into my code and made this possible using a filter. If you’d like to use a Google Fonts and need this subset, email me at support@generatepress.com and I’ll send you the updated files ๐
Once you have the updated files (or for others reading this once 1.2.4 is released), you can change the subset with this function:
add_filter('generate_fonts_subset','generate_change_fonts_subset');
function generate_change_fonts_subset()
{
return 'cyrillic-ext';
}
Note: This won’t work until GP 1.2.4 is released.
To add your own fonts, you can use @font-face in your CSS.
