for example echo "A" | wc -m yield 2 instead of 1. Why is this?
Thanks for the report; however, this is not a bug. In your example,
echo "A" really did output two characters: A and newline. Try:
echo A | od -tx1z
to see those characters, and try:
printf A | wc -m
to see the difference (since printf does not output a trailing newline).
