[R] replacing unicode characters

[Adrian Dusa]

Right on the point, Ivan, that was the issue. The output from l10n_info()
was:

$MBCS
[1] FALSE

$`UTF-8`
[1] FALSE

$`Latin-1`
[1] FALSE

$codeset
[1] "US-ASCII"

(and the locale was just "C")

I simply needed to write something like:
export LC_ALL='en_US.UTF-8'

before starting the child process, and everything looks good now.

Thanks a lot, much obliged,
Adrian
