I am not sure, it doesn`t exactly do the same. And to be fair 
std.array.replace use internaly std.algorithm.find which use in 
some scenario auto-decoding. So to be sure no autodecoding 
occured you must used something like that:

     string x = "some_text";
     auto res = std.array.replace(cast(byte[])x, [byte('_')], 
[byte(' ')]);
     writeln(cast(string)res);
