[Rd] Clarification for options(OutDec)

[Stephen Eglen]

The documentation for the OutDec option says that it should be a
'one-character string'; yet, if I try a unicode character, it doesn't seem
to work.  Are unicode chars not counted as one-character?

This is within the mac GUI, but I also see this on linux boxes.

> x <- '\u00B7'
> nchar(x)
[1] 1
> options(OutDec=x)
Error in options(OutDec = x) : invalid value for 'OutDec'

I don't think I've changed anything with my LANG settings, but here it
is anyway:

> Sys.getenv('LANG')
         LANG 
"en_GB.UTF-8"
