Duncan Jones commented on LANG-1299:
------------------------------------

Example implementation:

{code:java}
    public static int[] toCodePointArray(String s) {
        int[] result = new int[s.codePointCount(0, s.length())];
        int index = 0;
        for (int i = 0; i < result.length; i++) {
            result[i] = s.codePointAt(index);
            index += Character.charCount(result[i]);
        }     
        return result;
    }
{code}

> Java 7 doesn't offer a method for converting a string to an array of code points. This might be something we could add to {{StringUtils}}.
> {code:java}
> int[] codePoints = StringUtils.toCodePointArray(someString);
> {code}
