.Sh BUGS
Teletext's 6-cell (2x3) block characters are displayed as % characters
as they cannot be accurately reproduced in a terminal without special fonts.
(The NOS viewer and API uses a custom font with these characters in the
.Qq private use
0xF000 Unicode range.)
.Pp
Color ouptut is disabled by default in MinTTY on Windows.
This is because MinTTY redirects standard output.
Set
.Ev CLICOLOR_FORCE
to 1 to force color output.
