Can't use utf-8 variable names in RStudio console

Hi, I am running Chinese Win10. I have no problem on regular R console (running inside cmd.exe) to use Chinese characters in a variable name: 吴 <- 'abc' but the same statement running inside RStudio IDE shows: Error: invalid multibyte character in parser at line 1 the same statement runs fine in a RScript windows inside IDE. so it's purely a problem with console in IDE.. I have confirmed encoding in my project options is UTF-8. I can't find relavent options in Global Options to set console encoding to utf-8
