[Rd] sorting bug in R-devel?

2021-01-19 Thread Thierry Onkelinx via R-devel

Dear all,

My git2rdata package relies on a stable sorting. I've noticed that
some characters get a different position under R-devel under Windows
10. This is why the unit test of my package only fail in this
combination (https://cran.r-project.org/web/checks/check_results_git2rdata.html)

Below is a minimal example to illustrate the problem.

Best regards,

Thierry

data <- 
readLines("https://raw.githubusercontent.com/ropensci/git2rdata/master/tests/testthat/test_b_special.R";,
encoding = "UTF-8", n = 15)
eval(parse(text = paste(tail(data, -3), collapse = "")))
ds$a <- enc2utf8(ds$a)
print(ds$a) # input
Sys.setlocale(locale = "C")
print(sort(ds$a)) # sorted
print(order(ds$a)) # order
print(sessionInfo())

Re: [Rd] sorting bug in R-devel?

2021-01-19 Thread Peter Dalgaard

Not sure what happened between 4.0.2 and -devel, but you are using C collation, 
which assumes 7-bit single-byte characters, to sort multi-byte 8-bit encoded 
characters, which looks a bit risky.

2021-01-19 Thread Thierry Onkelinx via R-devel

Dear Peter,

Thanks for the feedback on the locale. Is there a better alternative for
the C locale? One that yields a consistent and stable sorting
independent of the R version and OS.

Best regards,

Thierry

base::icuSetCollate might be what you need. There are some decent
examples in the manual page on it.
