Yes, the first overload fails to match because U is inferred as 
immutable(char) rather than string:

     this(U)(U[] values...)
     if (isImplicitlyConvertible!(U, T))

This is because a single array can be passed to a typesafe 
variadic parameter rather than elements of that array type. And 
then immutable(char) doesn't convert to string.

I think a non-variadic overload could be added to make it work as 
expected.
