Subject: [ruby-core:48047] [ruby-trunk - Bug #7168] File.join trips over string encodings


Issue #7168 has been updated by nobu (Nobuyoshi Nakada).


Use UTF-8.

I don't think Darwin uses wide chars for file systems, though.

Bug #7168: File.join trips over string encodings

It seems like `File.join` is unable to handle string encodings that contain null bytes even though the string is properly encoded. This causes it to be unable to process inputs when the filenames on the system are encoded in this manner.

From an irb session:

    1.9.3p125 :013 > File.join("a".encode("UTF-16LE")).encoding
     => #<Encoding:UTF-16LE> 
    1.9.3p125 :014 > File.join("a".encode("UTF-16LE"), "".encode("UTF-16LE"))
    ArgumentError: string contains null byte
	from (irb):14:in `join'
	from (irb):14
	from /Users/andy/.rvm/rubies/ruby-1.9.3-p125/bin/irb:16:in `<main>'

I would expect the second command in that session to return "a/" just like `File.join("a", "")` does, but with the UTF-16LE encoding.

See <https://groups.google.com/forum/?hl=en&fromgroups=#!topic/puppet-dev/C1YODJxd9Ws> for where this came from.
