By using a font that is guaranteed to be provided by the system on which the app is running. Both Windows, macOS, iOS, and Android all make such guarantees.
Linux DEs generally don't, but perhaps they should, given that open fonts with decent quality and extensive coverage are out there. Something like the Noto family.
And if you generate a set of bitmaps/sprites of individual glyphs from the font (e.g. to use as a bitmap font in a game), is that different to shipping an image with more specific uses of the font baked in, e.g. a logo/title image?
