It is not inevitable. Simply disallow the 2 codepoint sequences - the single one 
has to be used instead.

There is precedent. Some characters can be encoded with more than one UTF-8 
sequence, and the longer sequences were declared invalid. Simple.

I.e. have the normalization up front when the text is created rather than 
everywhere else.
