[R] .libPaths() can not deal non-latin characters?

[Jinsong Zhao]

The folder is there. The problem is caused by Sys.glob() in .libPaths(). 
Sys.glob() will return character(0) when the path contains Chinese 
characters.

Here is another demo:

 > dir.exists("c:/Users/zjs/Desktop/中文/R")
[1] TRUE
 > Sys.glob("c:/Users/zjs/Desktop/中文/R")
character(0)
 > Sys.glob("c:/Users/zjs/Desktop/中*/R")
character(0)
 > Sys.glob("c:/Users/zjs/Desktop/*文/R")
character(0)
 > Sys.glob("c:/Users/zjs/Desktop/*/R")
[1] "c:/Users/zjs/Desktop/中文/R"

Best,

Jinsong
