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

[Tomas Kalibera]

Dear 叶月光,

as discussed on this thread, Ivan Krylov found a bug in R, which could 
be causing the problem you have run into. To confirm this is the cause, 
could you please check outside R (say in explorer) if you have any file 
with a very long name in the directory? And if so, does moving that file 
away make the problem disappear? Files with up to 80 characters couldn't 
trigger this bug.

A workaround for this bug is not to use file names with more than 80 
(possibly all Chinese) characters.

The content of a file (or whether the content is in UTF-8 or not) cannot 
be influencing this problem directly, neither list.files() nor Windows 
looks into the files when listing them.

The bug Ivan found is not a regression: older versions of R may crash 
when you have such long file names. So there would be no point staying 
with an older version to overcome this problem: the only reliable 
work-around I can think of is use reasonably short file names.

Best
Tomas
