Use 'echo -e' to evaluate ascii codes in message.

[bacek]

Without -e echo will output unicode as-is. E.g.:

fmt \xE2\x9C\x93
test \xE2\x9C\x93

With -e it's actually evaluating them into
fmt ✓
test ✓

Can we use printf instead of echo -e?

[bacek]

My bash-fu isn't strong enough. I couldn't figure out how to emulate '''echo " $result"' with printf. Using %s print all lines left-aligned.
