npm install strip-combining-marks

Via Bower:

bower install strip-combining-marks

Via Component:

component install mathiasbynens/strip-combining-marks

In a browser:

<script src="strip-combining-marks.js"></script>

In Node.js, io.js, Narwhal, and RingoJS:

var stripCombiningMarks = require('strip-combining-marks');

In Rhino:

load('strip-combining-marks.js');

Using an AMD loader like RequireJS:
