Ah. I think I've tracked down the problem. The term is(Range ==  
Unqual!(T)[]) used to be true for a string and char[], and now it's  
properly being evaluated to false, which in turn causes the wrong static  
if branch to compile. So yes, this is a regression bug. You can fix by  
replacing the conditional (at line 1594) with:

         // note, we disable this branch for appending one type of char to
         // another because we can't trust the length portion.
         static if (is(typeof(_data.arr[0..1] = items[0..1])) &&
                    is(typeof(items.length) == size_t))

Or you can try out my patch to appender:
