I think you've misunderstood. RFC 2244 allowed for Unicode here already, 
but it never specified any Unicode normalization rules.
This document actually restricts the allowed characters to a subset of 
ASCII, because of existing uses in various IMAP (and Sieve) extensions. 
So no Unicode normalization would be needed.

Having said that, the document might not be very clear on this.

I will let the author comment on this.

Good catch.
