An optional parameter to source() function which would translate all UTF-8 characters in string literals to their "\Uxxxx" codes sounds as a great idea (and I hope it would fix 99.9% of problems I have - because that is the way I overcome these problems nowadays) - and the same behaviour in command line...
I was not suggesting to convert to \Uxxxx in source(). Some users do it in their programs by hand or an external utility. Source() in principle could be made work similarly to eval(parse(file,encoding=)) with respect to encodings, via other means, we will consider that but there are many remaining places where the conversion happens - a trivial one is that currently you cannot print the result of the parse() from your example properly. Maybe you don't trigger such problems in your scripts in obvious ways, but as I said before, if you want to work reliably with characters not representable in current native encoding, in current or near version of R, use Linux or macOS.
