Also, the 'at a minimum' information requested by the posting guide is
essential here (which OS and locale, in particular). In general file
names not in the locale's encoding are unsupported.
An off-list reply indicated this was Windows XP. Although the message
body was unreadable, the gist is in the subject line.
From ?list.files under Windows
path must specify paths which can be represented in the current
codepage.
whereas ?file.exists says
Most of these functions accept UTF-8 filepaths not valid in the
current locale.
So this is documented behaviour.
[For anyone curious as to why list.files is different: note that it does
regexp pattern matching. Adding support for Unicode file paths would
not be impossible but it would require hundreds of lines of Windows-only
code.]
