[R] Windows OS, R and unicode

[Prof Brian Ripley]

Richard,

At present the \uxxxx notation only works on Windows in CJK locales, and 
only to represent characters defined in the locale in use.  Now it seems 
that _does_ include the signs you mention in Japanese.  So it is possible 
that if you start R with

Rgui LC_CTYPE=ja

then this will work: it does for me in 2.6.0 (and I see no reason why it 
would not in 2.5.1, but I updated my Windows box yesterday).

I should perhaps add that only windows() devices will work and not say 
pdf().
