You probably already know that basic script coverage information is
stored internally in OpenType fonts in the OS/2 table.
https://docs.microsoft.com/en-us/typography/opentype/spec/os2
Parsing the bits in the "ulUnicodeRange..." entries may be the
simplest way to get basic script coverage info.
OpenType fonts also include script coverage information in the
OpenType tables. A font with an OpenType table for a script would be
likely to have at least some complex script shaping abilities for that
script.
