Another way to see what is going on is do this:

Y=binary_to_list(<<"{get,\"user\",\"wilson\",\"lname\"}">>).
[io_lib:format("~c~w",[X, X])||X <- Y].

You'll see \" in the output, but the ascii numeric value for that
character is 34.

Then if you go and look and see what 34 is on the ascii table below,
you'll see it is ".
