Well, bytes are bytes until you decide to look at them in a 
certain way. Yea, the input may be invalid as per the spec; 
however, if mojibake indicates that you're decoding them twice, 
you're probably doing something that's at least unnecessarily 
inefficient.

Maybe you're passing the bytes as char arrays to std.algorithm, 
which produces dchars, which are then being cast into char before 
decoding again? I think that would produce this sort of mojibake.
