Yeah, that seems like a bad design choice. If you look at the spec [0], you can see that they only use "23456789CFGHJMPQRVWX" in the codes. They apparently scored the letters based on how well they can spell 10000 words in 30 languages, without thinking about character similarity. If they had involved actual humans instead of counting letter frequency, they might have noticed that the letter W looks similar to VV, and that its English name is "double U". And tried a letter like N or Y, which would be much harder to confuse.
