Kinda-sorta, but it won't quite work for this.  The high-order answer
is to reference IDNA 2008 (RFC 5892 will do) and say that characters
that are PVALID are acceptable here.  The trouble with that is that it
limits you to lower case characters: all the upper case characters are
DISALLOWED.  It could work to say "PVALID characters and their upper
case versions."

But, really, I think Brian's right that we don't need to worry,
especially because there's the designated expert in the middle, who
can say, "PILE OF POO"?  Really?  Why do you want to use that
character?
