When using R on my Gentoo machine, whether in interactive or in batch
mode, calling `help()' causes the following error:
    Error in strsplit(txt, "\n", fixed = TRUE) : 
      'split' string 1 is invalid UTF-8
When in interactive mode, typing any function with an opening bracket
(eg. `help(') and then pressing tab (intending to get a command
completion) causes the same error.

Above is the situation in the default locale on my machine,
`en_GB.UTF-8'; and with LANG=C, this does not happen.

My Gentoo system is updated daily with global ~amd64 keyword in use.
Available locales as following:
	C, en_GB.UTF-8, POSIX
USE flags of dev-lang/R (version: 2.13.1) as following:
    X bash-completion cairo jpeg nls openmp perl png readline -doc -java
    -lapack -minimal -profile -static-libs -tk

Sorry to report this in the mail list, but there's some difficulties in
accessing <bugs.gentoo.org> for me. Please tell me if this is
inappropriate.
