Sure.  There are lots of ways to implement this, which is why IETF
standards normally specify wire formats.  What you do in the privacy
of your own implementation has no interoperability implications.  But
if you want to hand a U-label to anyone else, it had better be UTF-8
in NFC, or else it can't be a U-label.
