However symbol frequency is also significant for entropy.
Do you think 1 in 25 four letter passwords contain a backtick?
If you were brute forcing an ASCII password (no whitespace), would you naively cycle from ! up to ~ for each character?
The context is randomly generated passwords, so dictionary attacks (or other attacks that look at the plaintext from a Huffman encoding perspective) aren't really relevant.
