Yes @jongyc in this way anyone can pick font weights and character sets in the Font Picker quickly and comfortably. If you want these here, they are available in your subject.
The weight of custom font (wingdings font) (thin, light, regular, etc.) determines the size of the font at the front end. It can be a perfect way to differentiate titles and subtitles, to increase the overall typography of the pages, and more.
Character sets are particularly ideal for multi-language sites as they allow you to use Latin, Cyrillic, Greek, etc. Although not all fonts allow additional character set you can pick one or more character sets.
