Ouch, of course.  How stupid of me.  That explains why it didn¡Çt work
under 1.8.7 either.

The point still remains valid on Windows, however:

% mkdir t
% touch t/¢ª
% ruby -v -C t -e 'Dir.foreach(".") {|e| printf "%p, %p, %p\n", e,
e.encoding, File.file?(e)}'
ruby 1.9.3dev (2011-09-13 revision 33263) [i386-mingw32]
".", #<Encoding:Windows-1252>, false
"..", #<Encoding:Windows-1252>, false
"?", #<Encoding:Windows-1252>, false

Hm, I guess here the result of Dir.foreach is broken.

Here¡Çs another case:

% ruby -v -rfind -e 'Find.find("t").each{ |e| printf "%p, %s, %p,
%p\n", e, e.dump, e.encoding, File.file?(e)}'
"t", "t", #<Encoding:UTF-8>, false
"t/?", "t/?", #<Encoding:ASCII-8BIT>, false

Equally broken, I guess.
