Bug #13655: external encoding named "-" (doc issue or…?)

• Status: Closed
• Assignee: stomar (Marcus Stollsteimer)

[shyouhei (Shyouhei Urabe)]

IO.new's document explicitly states that it accepts "-" as external encoding:

https://github.com/ruby/ruby/blob/d0015e4ac6b812ea1681b1f5fa86fbab52a58960/io.c#L7790

which is not true.

% ruby -ve 'IO.new(0, external_encoding: "-")'
ruby 2.5.0dev (2017-06-09 trunk 59055) [x86_64-darwin15]
Traceback (most recent call last):

        1: from -e:1:in `new'

I think it a doc issue.

We looked at this issue at yesterday's developer meeting and none of attendees remembered there has been any plans to have this feature. It seems to be a doc issue. Please delete this part.
