Hi all-
I tried searching before posting, but this is one of those tricky
questions to search for. My issue is this: within the R.app gui, I can
use extended characters in plot labels without any issue (specifically
in my case the ∂, lowercase delta), for example:
plot(c(1:10) ~ c(1:10), main="∂foobie bletchƒ")
However, when I try to do the same in a script from the terminal
(interpreted by Rscript), I get a bunch of errors related to character
encoding:
....
conversion failure on '∂foobie bletchƒ' in 'mbcsToSbcs': dot
substituted for <e2>
....
Is there a way to make this work? Or is Rscript not equipped to handle
multibyte characters?
It seems your'e running Rscript in a locale that doesn't support
unicode (probably C). Make sure you use UTF-8 locale (e.g.
LANG=en_US.UTF-8)
Maybe: but because he blatently ignored the posting guide, we don't
know.
Another possibility is that he is using a graphics device that does
not support those characters (and again, we have not been told).
Using Greek characters requires the postscript() and pdf() devices to
be told to work in Greek, as their help pages (and the R manuals)
makes clear. It is those graphics languages (and not Rscript) which
do not support Unicode. You will also need viewers that support the
Greek characters ....
