Capabilities, derived from terminfo, environment variables, and queries

Fields

colors: c_uint

size of palette for indexed colors

utf8: bool

are we using utf-8 encoding? from nl_langinfo(3)

rgb: bool

24bit color? COLORTERM/heuristics/terminfo ‘rgb’

can_change_colors: bool

can we change the palette? terminfo ‘ccc’

halfblocks: bool

we assume halfblocks, but some are known to lack them

quadrants: bool

do we have (good, vetted) Unicode 1 quadrant support?

sextants: bool

do we have (good, vetted) Unicode 13 sextant support?

braille: bool

do we have Braille support? (linux console does not)
