[Rd] R-4.3 version list.files function could not work correctly in chinese

[Yihui Xie]

Yes, I participated in the discussion. Basically dir() failed to list all
files since R 4.3.0 when filenames start with Chinese characters. I don't
have a Windows machine to test it, but this might be a minimal reproducible
example:

file.create("常用代码.R")
dir()

The OP said dir() would return "常用代码.R" in R.4.2.2 but not in R 4.3.0. In
the same discussion another person mentioned that the problem could also be
related to the file encoding, i.e., if the file content is encoded in
UTF-8, it could be recognized by dir(), but not in ANSI.

Yihui
