I was responding to Ludovic.

My problem is when it is not valid UTF-8.

Well, execute these commands from bash:
$ touch $'\xee'
$ touch xyz
$ ls -a
. .. ''$'\356' xyz
Then, execute this guile program:
========================================================================
(let ((dir (opendir ".")))
(let loop ()
(let ((filename (readdir dir)))
(if (not (eof-object? filename))
(begin
(if (access? filename R_OK)
(format #t "~s\n" filename))
(loop))))))
========================================================================
It outputs:
".."
"."
"xyz"
skipping a file. This is a security risk. Files like these appear easily
when extracting zip files, for example.
