I'm not sure what they are being posted as examples of there? Can a bidi char in a string literal be succesfully used in the sort of attack in the OP, a "Trojan Source" attack? If so, that is devious! It's not clear to me if those example show that though. They show bidi characters being highlighted in a string literal, right. My hypothesis was that such could not be part of a "trojan source" attack... but this stuff is confusing and I could have it wrong?
