Something goes wrong with the locale setting when the R child process
is being launched. For example,

Rscript -e 'cat("\ue7\n")'
# ç

but:
LC_ALL=C Rscript -e 'cat("\ue7\n")'
# <U+00E7>

When preparing \ue7 for output, R decides that it's not representable
in the session encoding. What's the output of sessionInfo() and
l10n_info() in the child process?
