See the exact byte sequence of an R string?

Question

How can I get the byte sequence of a particular UTF-8 string? I'm seeing what looks like some bug in the regex engine which is only triggered in some edge cases, and I'd like to know exactly what data it's working on.

Answer 1

Maybe charToRaw?

> charToRaw("R-string")
[1] 52 2d 73 74 72 69 6e 67
