one of the jamo sequence he raised was illegal one ( choseong+jungseong+filler is illegal,
choseong+jungseong is enough). stand-alone filler (looks like space) is illegal use.

NFC already  map modern jamo sequences into modern hangul syllables. But,
Some illegal jamo/filler sequence are left unfiltered/unchanged and that cencern was raised
in the I-D.  I had proposed  such illegal/abnormal jamo/filler sequence should be
prohibited by nameprep. But, some nameprep authors are reluctant  to 
hard code such cases, because current UTC has no standard code for such case.
Instead, filtering out by registrations was proposed by them. 
currently not resolved issues.
