Determine each character of a string if it contains full width characters

I want to manually check each character of a string for whether it contains any full width characters. Can someone help me?

This is what I have so far:

public boolean areAnyFullWidth(String input) {
    for (char c : input.toCharArray())
        if ((c & 0xff00) == 0xff00)
            return true;
        return false;
}

If you know the start and end unicode full width range then things are very simple.

Say the range is 0xFFOO to 0xFFEF:

public boolean areAnyFullWidth(String input) {
    for(char c : input.toCharArray())
        if(c >= 0xFFOO && c <= 0xFFEF)
            return true;
        return false;
}
