Fallback symbols

Some terminals do not support (all) Unicode characters, and on these reasonable ASCII substitutes are used:

#> √   tick
#> x   cross
#> *   star
#> █   square
#> [ ] square_small
#> [█] square_small_filled
#> ( ) circle
#> (*) circle_filled
#> ( ) circle_dotted
#> (o) circle_double
#> (o) circle_circle
#> (x) circle_cross
#> (|) circle_pipe
#> (?) circle_question_mark
#> *   bullet
#> .   dot
#> ─   line
#> =   double_line
#> ... ellipsis
#> >   pointer
#> i   info
#> ‼   warning
#> ≡   menu
#> ☺   smiley
#> ┌─┐ mustache
#> ♥   heart
#> ^   arrow_up
#> v   arrow_down
#> <   arrow_left
#> >   arrow_right
#> (*) radio_on
#> ( ) radio_off
#> [x] checkbox_on
#> [ ] checkbox_off
#> (x) checkbox_circle_on
#> ( ) checkbox_circle_off
