Hi,
in line 7 and 16 the printf
should be extended to support systems with different number encoding:
-7 fill=$(printf "%.0f\n" $progress)
+7 fill=$(LC_NUMERIC="en_US.UTF-8" printf "%.0f\n" $progress)
-16 percent=$(printf "%0.2f\n" $percent)
+16 percent=$(LC_NUMERIC="en_US.UTF-8" printf "%0.2f\n" $percent)
