I asked the same question on the D.learn group recently. Literals like 
that don't have a particular encoding. The programmer must specify 
explicitly to resolve ambiguities: "hello world"c or "hello world"w.

I think the solution is to take advantage of templates and use template 
constraints if the template parameter is too flexible.

Another approach might be to use dchar within the application and use 
other encodings on the intefraces.
