This can be narrowed down to
Sys.setlocale("LC_CTYPE","C")
x2 <- "\u00e7"
x1 <- iconv(x2, from="UTF-8", to="latin1")
x1 < x2 # FALSE or NA
In R 4.0 it returns NA, in R-devel it returns FALSE (when running in
CP1252 locale on Windows).
It is the same character, only the encoding is different,
Hi R developers,
There seems to be breaking change in base::order on Windows in
R-devel. Code below yields different results on R 4.0.0 and R-devel
(2020-05-22 r78545). I haven't found any info about that change in
NEWS. Was the change intentional?
Sys.setlocale("LC_CTYPE","C")
