Twig - Get corresponding alphabet letter in loop

Question

I want to use the loop.index variable in twig to get the corresponding alphabet letter (1 = A, 2 = B, etc).

{% for item in form.items %}
     {% set nom_item = 'Item'~loop.index %}
{% endfor %}

How could I do to get alphabet letter in loop ? I can't find a twig function for that.
