I read from The Ruby Programming Language that nil can be specified as "binary" or "ascii-8bit".
The book give a sample code on Page 61:

text = stream.readline.force_encoding("utf-8")
bytes = text.dup.force_encoding(nil) # nil encoding means binary

However, force_encoding(nil) doesn't work on Windows, it will raise a TypeError.
Maybe it's a bug for Windows?

• Status changed from Open to Rejected

The feature is changed on 1.9.2; now nil is not a valid argument.
