Once again, we are not talking about visual appearance (i.e. you reading the text with your mark 1 eyeballs) but rather accessibility where the text may be spoken, displayed in Braille, etc. The audio results will not be up to the results from the use of a full-fledged SSML but it is better than nothing.

But if the program did not read the <i> with emphasis, then there's a problem with the program doing the reading.
