It depends on the exact character set, but I think that is roughly the 
idea. Note, you would also likely use some key stretching process (i.e., a 
"password based key derivation function"), which would make a somewhat 
shorter password effectively as difficult to crack as a longer password 
that wasn't key stretched. So, you could get 256-bit level of protection 
with a slightly shorter password.
