Yea, I came to the same conclusion while working on it. :-)

The solution I have is (i) in uniform!"[]" check that !is(ResultType == dchar) 
before checking the condition for calling uniform!ResultType, and (ii) inside 
uniform!T, place

     static if (is(T == dchar))
     {
         return uniform!"[]"(T.min, T.max, rng);
     }
