This comment is doesn't add much information from what one can get just by
looking at the class name. Please extend it to make it clear what this class is
responsible for and how it's should be used.

I am not sure I like having the indirection anymore, I can remove this class
entirely now. The original plan was to deal with keyboard events with keycodes
but then I found the new method to send text events... So I was waiting to see
how the implementation worked out to see if I still needed this class to help
out. I am not sure yet.

+class KeyboardInterpreter {
+ public:
+  explicit KeyboardInterpreter(ChromotingSession* input_stub);
+  ~KeyboardInterpreter();
+
+  // Delegates to |KeyboardInputStrategy| to covert and send the input.
+  void HandleTextEvent(const std::string& text, uint8_t modifiers);
+  // Delegates to |KeyboardInputStrategy| to covert and send the delete.
+  void HandleDeleteEvent(uint8_t modifiers);
+
+ private:
+  std::unique_ptr<KeyboardInputStrategy> input_strategy_;
+
+  DISALLOW_COPY_AND_ASSIGN(KeyboardInterpreter);
+};
+
+}  // namespace remoting
