the practical answer is that you are asking for problems when you accept more than the 'commonly seen' non-alpha chars.
The "practical" answer given is in violation with RFC 822. I would not be shocked that the people who are writing such bad implementations are YOUNGER than the 1982 draft of RFC 822.
To advocate ignoring RFCs leads down a path where the Internet stop working as without RFCs and following the RFCs the internet does not work.
