UTF8-form of a label may be used as protocol elements , in addition to
presentation forms.
In the latter case, there will be no problem as you said above: just
display it.

But, in the former case of being used as protocols elements, utf8-form
label length limit is
of our concern. IDNA drafts does not rule out that utf-8 form of labels
may be used as protocol
elements. This will clairfy my point.

Thanks.
