>> Exact semantics of formatting characters aside, it is best to define plain >> text as a stateless stream.

That would be fine and the characters discussed would be, in my opinion, two useful additions to Unicode. If a two word phrase were to be typeset within a plain text file then each letter of the two words would need to have an instance of the COMBINING ITALICIZER after each letter of the word. Would one add an instance after the space character that is between the words? William Overington 27 March 2015
