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

[Jinsong Zhao]

Hi there,

I have a computer run Win10 with user names in Chinese. I installed R on it. It can run normally. When I installed a package, for example, ada, then the library would be installed into "C:/Users/中文/Documents/R/win-library/3.6", where "中文" is my user name.  

> library(ada)
Error in library(ada) : there is no package called ‘ada’

> .libPaths()
[1] "C:/Program Files/R/R-3.6.1/library"

> .libPaths(c("C:/Users/中文/Documents/R/win-library/3.6", .libPaths()))
> .libPaths()
[1] "C:/Program Files/R/R-3.6.1/library"

you will find that .libPaths() does not accept the path with Chinese (I think non-latin characters may not be accepted). 

I also tried to install the package to other directory with Chinese character, and then set the .libPaths, and failed. 

Is it the features?

Any hints? Thanks in advance.

Best,
Jinsong
