I suggest expert review by a native speaker in addition to reviewing

I haven't looked into this in the context of IRI.

I'll give the same answer as above.

Section 4.4 refers to visual similar characters (sometimes called 
"confusables").  Your text talks about presentation whether visually 
or read out loud.  Both texts note that there may not be a technical 
solution to the problem.  Your text conveys the idea that this is a 
difficult problem to solve.  I have a preference for the text in 
Section 4.4 because of its second paragraph.  I would put in 
a  pointer to UTR36 as that document is more elaborate.
