Solomon Rutzky shares some thoughts:
Since the new
UNISTRfunction doesn’t provide new functionality, only convenience (“syntactic sugar” as some would say; see comment below), I would argue that it should not only use a more standard syntax, but also not waste the opportunity and provide more substantive convenience by handling several commonly used escape sequences. I suspect that the number of times people would use “\n” is several orders of magnitude more than the number of times people would inject emojis or other non-keyboard characters. Even better would be to incorporate common escape sequences into standard string parsing.
