Issue #9712 has been updated by Zachary Scott.

Status changed from Assigned to Closed

I think the current documentation explains this well, so closing.

```
/*
 *  call-seq:
 *     Dir.entries( dirname )                -> array
 *     Dir.entries( dirname, encoding: enc ) -> array
 *
 *  Returns an array containing all of the filenames in the given
 *  directory. Will raise a <code>SystemCallError</code> if the named
 *  directory doesn't exist.
 *
 *  The optional <i>enc</i> argument specifies the encoding of the directory.
 *  If not specified, the filesystem encoding is used.
 *
 *     Dir.entries("testdir")   #=> [".", "..", "config.h", "main.rb"]
 *
 */
```

Bug #9712: Dir.entries replace Unicode character with questionmarks
https://bugs.ruby-lang.org/issues/9712#change-48097

* Author: Thomas Thomassen
* Status: Closed
* Priority: Normal
* Assignee: Zachary Scott
* Category: doc
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-04-07 trunk 45528) [i386-mswin32_100]
* Backport: 2.0.0: DONTNEED, 2.1: DONTNEED
----------------------------------------
My basis when testing this is that I have a computer with English OS - codepage Windows-1252. The tests might yield different result if the Windows codepage is different - so please pay attention to that if you are unable to reproduce.

Given a folder named "Foo" which contains a sub-folder "Ƥ" ("\u3066\u3059\u3068") Dir.entries("Foo") will return:
[".", "..", "???"]

The characters that doesn't fit my filesystem codepage is translated into question marks.

I would have expected the strings returned to be in some Unicode format.
