It should support appending single code units:

---
alias String = RCString;

void main()
{
     String s = "abc";

     s ~= cast(char)'0';
     s ~= cast(wchar)'0';
     s ~= cast(dchar)'0';

     writeln(s); // abc000
}
---

Works with C[], fails with RCString. The same is true for 
concatenation.
