Reply To: :after for input[type=button]

I mean these

 <input type="button" class="red" value="Input button" />
    <input type="submit" class="red" value="Input submit" />
    <input type="reset" class="red" value="Input reset" />

I’ve set up a webfont icon kit using icomoon and I want to apply icons such as a arrow right for submit or a cross for reset
