You can make your own range, however look at this function first 
(second example)
https://dlang.org/phobos/std_algorithm_iteration.html#.splitter

     // 1) might need to cast your wchar[] to wstring first
     // 2) also assumes that 'the word' is separated by whitespace
     foreach( word; chars.splitter(' '))
     {

     }

or this one, which is a bit more smarter about what "the word" 
means
https://dlang.org/phobos/std_array.html#.split

     import std.array : split;

     wchar[] str = cast(wchar[]) "some random stuff blah blah"w;
     foreach(w; str.split())
     {
         writeln(w);
     }

Anyway in both cases using dmd -vgc flag shows no GC allocations 
done.
