The BIP39 wordlist has been updated to consider certain character pairs as similar. These pairs have been filtered from a similarity matrix provided by Gregory Maxwell in an old wordlist solver code. The goal is to avoid confusion when encoding public and private keys, and to prevent words that could look similar when written down. The character pairs that are now considered similar include 'a' & 'c', 'a' & 'e', 'a' & 'o', 'b' & 'd', 'b' & 'h', 'b' & 'p', 'b' & 'q', 'b' & 'r', 'c' & 'e', 'c' & 'g', 'c' & 'n', 'c' & 'o', 'c' & 'q', 'c' & 'u', 'd' & 'g', 'd' & 'h', 'd' & 'o', 'd' & 'p', 'd' & 'q', 'e' & 'f', 'e' & 'o', 'f' & 'i', 'f' & 'j', 'f' & 'l', 'f' & 'p', 'f' & 't', 'g' & 'j', 'g' & 'o', 'g' & 'p', 'g' & 'q', 'g' & 'y', 'h' & 'k', 'h' & 'l', 'h' & 'm', 'h' & 'n', 'h' & 'r', 'i' & 'j', 'i' & 'l', 'i' & 't', 'i' & 'y', 'j' & 'l', 'j' & 'p', 'j' & 'q', 'j' & 'y', 'k' & 'x', 'l' & 't', 'm' & 'n', 'm' & 'w', 'n' & 'u', 'n' & 'z', 'o' & 'p', 'o' & 'q', 'o' & 'u', 'o' & 'v', 'p' & 'q', 'p' & 'r', 'q' & 'y', 's' & 'z', 'u' & 'v', 'u' & 'w', 'u' & 'y', 'v' & 'w', and 'v' & 'y'. The author invites comments on the current wordlist and suggests that they are slowly moving towards a final list.
