Trying to write some logger enhancements I'd like to deal with ANSI codes interpretation, and it seems that it's not working with the standard `io.putstring` method neither with `print` I wonder there is a way to do something such as 

`echo -e "\u001B[31mSome_red_txt"` in bash

Seems [other languages](https://stackoverflow.com/questions/2616906/how-do-i-output-coloured-text-to-a-linux-terminal) can do it but I can't in Eiffel.
