The "normalization" is when you import to rich text, you don't want 
competing formatting instructions. Getting styled character codes 
normalized to styling of character runs is the most difficult, that's 
why the abuse of math italics really is abuse in terms of interoperability.

Other schemes, like a VS per code point, also suffer from being 
different in philosophy from "standard" rich text approaches. Best would 
be as standard extension to all the messaging systems (e.g. a common 
markdown language, supported by UI).
