Just by reading the code, LockingTextWriter can "put" only the dchar 
type. This is from std.stdio:

         /// Range primitive implementations.
         void put(A)(A writeme) if (is(ElementType!A : const(dchar)))
// ...
         void put(C)(C c) if (is(C : const(dchar)))

I haven't tried it myself, but changing the return type of 
Sequence.front() to dchar would work.

 Just by reading the code, LockingTextWriter can "put" only the dchar=20
 type. This is from std.stdio:
=20
          /// Range primitive implementations.
          void put(A)(A writeme) if (is(ElementType!A : const(dchar)))
 // ...
          void put(C)(C c) if (is(C : const(dchar)))
=20
 I haven't tried it myself, but changing the return type of=20
 Sequence.front() to dchar would work.

 Just by reading the code, LockingTextWriter can "put" only the dchar
 type. This is from std.stdio:

           /// Range primitive implementations.
           void put(A)(A writeme) if (is(ElementType!A : const(dchar)))
 // ...
           void put(C)(C c) if (is(C : const(dchar)))

 Sequence.front() to dchar would work.




I was wrong anyway. I think is(C : const(dchar)) means if C can 
implicitly be convertible to dchar. That is the case for char and wchar, 
so that can't be the reason.

 thanks ali i have try but no same error


Sorry, no more ideas here. :(
