I don't know what you could be referring to.  Suppose X is a string
consisting entirely of uppercase Greek letters.  X is not nameprepped,
because nameprepped things don't contain uppercase.  X contains no ASCII
characters.  ToUnicode(X) equals X, exactly, which means it is perfectly
acceptable to display X.
