Setting LC_ALL=C in the environment does that.
However, it seems pretty unlikely that you really want to do that in
Sweden. The issue seems to be that you have the encoding set to an invalid
value
>locale:
>C/UTF-8/C/C/C/C
is wrong. So try setting LC_ALL=sv_SE.UTF-8, or if you only want the
character set to be UTF-8, LC_CTYPE=en_US.UTF-8
I just tested
blacklark% env LC_CTYPE=sv_SE.UTF-8 R
> Sys.getlocale()
[1] "C/sv_SE.UTF-8/C/C/C/C"
and it is displaying correctly on X11 plots.
I suggest you track down the incorrect setting of LC_CTYPE.
