    #                 sans-serif and serif, removes the FCC fonts (which must be
    #                 provided by the system or downloaded from the web),
    #                 replaces standard CJK with low quality CJK, removes
    #                 historic script fonts, and replaces colored emojis with

    #                 Korean. This package is ~8.3MB.

    #                 Roboto's Basic Latin characters. Everything else must be
    #                 provided by the system or downloaded from the web. This
    #                 package is ~40.0KB.
    # NOTE: When bold is needed, but unavailable, it is typically synthesized,

    #       a bold font. However, this does not occur with low quality CJK,
