Currently OSM allows most characters:

2 usernames with " in their name
35 users with ' in their name
49 users with @ in their name
4527 users with space in their name

And there are tons of software out there which does not support anything
than AlphaNumeric + handful of specials like -_+-.

Would also be a valid email address although its of no use as most entry
forms will only accept a domain part with at least a single dot ...

Also the case sensitivity worrys me a bit - there is software out there
which will fix the case for you on sending - IIRC Lotus Notes has got
this (bad) habit ...
