To be fair, while allowing "special characters" increases the possible keyspace, allowing them doesn't significantly increase the likely keyspace because even the people who use them don't use them in the same frequency that they use "normal" characters.
There's a difference between 64 random bits and 7 random seven bit quantities with an 8 bit random quantity inserted somewhere in the sequence. The latter is closer to 56 random bits. (Yes, I know that A-Za-z0-9 is not 7 random bits.)
