Bad potential interaction between required Unicode normalization and Japanese language text

From "MURATA Makoto (FAMILY Given)":

 

Human names in the Japanese language will be modified by NFC.

 

I propose to replace "required" in

 

"To aid Reading Systems in implementing consistent searching and sorting behavior it is required that Unicode Normalization Form C (NFC) be used (See http://www.w3.org/TR/charmod-norm/)."

 

by "recommended" at least.
