If you change the source to include the explicit characters (i.e. use
pattern = c("?", "?") instead of pattern=c("\u03bc", "\u00b5")), does
that help?
It may cause other issues: WRE recommends against including UTF-8 chars
in source code.
If that doesn't solve the problem, then it looks like an issue with
Roxygen2. I don't know if there's a way to tell it not to convert \u
escapes into the corresponding character. If there isn't, it seems like
that's something they should add. As a workaround, is there a way to
say that this one particular .Rd file should be edited by hand, instead
of auto-generated?
I don't think roxygen2 intentionally converts \u sequences, I think this is just a consequence of the parse() + deparse() roundtrip: x <- '"\\u03bc"' charToRaw(x) #> [1] 22 5c 75 30 33 62 63 22 y <- deparse(eval(parse(text = x))) charToRaw(y) #> [1] 22 b5 22 Bill, please report a roxygen2 issue at https://github.com/r-lib/roxygen2/issues and we can probably fix this. Thanks! Gabor
