That's for when you support multiple types of input. I have it because I switch back and forth from English to Japanese. When I type Japanese, it has a Japanese symbol up there. You can edit these settings in the International preferences pane.

It's used for more than switching languages. You'd want to keep it if you want to access to the Character Palette or Keyboard Viewer (OS X version of Keycaps) easily. If not, then don't worry about taking it off the menubar.
