I have test this code in a FreeBSD. The locale of the OS is "C".

After starting R, I use `Sys.setlocale(category = "LC_ALL", locale = 
"zh_CN.UTF-8")' to set the internal locale of R to "zh_CN.UTF-8".

I save the above command in a file with encoding of UTF-8. And in R, I 
use `source("a.txt", encoding="UTF-8")'. I can get a figure, with 
correct characters (in Chinese) in all positions except that in legend 
(I don't know why?).
