I'd consider using `mkpasswd -l 15 -s 0` just to avoid any such problems. 15 random alphanumerics is already plenty complex, 62^15th possible combinations, without needing to mix in special characters.

btw, thats 768,909,700,000,000,000,000,000,000 possible passwords. 768 septillion, using the aamerican 'short scale' naming convention. if you could brute force try 10000/second, it would merely take 24,365,800,000,000 centuries (24 trillion).
So do you think a password like
Nxw7TnC2^}%(}tEz is strong enough? :-)
I developed a Java program that generates 20 passwords (each of 16 characters) at a time, I've attached it for anyone who might be interested. I have put it under the GPL version 3, but I might consider releasing under other licences.
