How can I use accented Latin characters like these (or any other unicode char really) in my echo statements comments?                   
How to save and use latin unicode in a shell script?
bash;shell;unicode
Modern Unixes use utf-8, this is the same as 7bit-ascii, but has extension bytes for other unicode characters. If your terminal is set to utf-8, then you can paste in the characters in you question.e.g. echo        If you wish to type them, then I suggest enabling a compose key.Then you can type compose A ~ for . Or compose : ) for .
