Terminal control/Unicode output is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
The task is to check that the terminal supports Unicode output, before outputting a Unicode character. If the terminal supports Unicode, then the terminal should output a Unicode delta (U+25b3). If the terminal does not support Unicode, then an appropriate error should be raised.
UNIX Shell
<lang sh>if
awk ' BEGIN { if (ENVIRON["LANG"] ~ "UTF") exit 0 # exit ok exit 255 # exit false }'
then
# This terminal supports Unicode printf "\u25b3" # Requires a Unicode compatible printf
else
echo "HW65001 This program requires a Unicode compatible terminal" >&2 exit 252 # Incompatible hardware
