It's not clear how to interpret that smiley face. The "mapping being 
specified elsewhere" is not relevant to your question. Section 5.4 
lists requirements on any client that is doing lookup. What the 
bullet you mention requires is that every DNS client, even ones with 
no preprocessing in the local environment, MUST have the ability to 
determine whether or not each string (label) is in NFC form.
