Annoying: cannot write ' user=" Iñaki ' in a Ruby1.9 script

ruby-talk

Hi, I'm really annoyed, please try this:

Open a file (in a UTF-8 system as any modern Linux) and write:

script.rb

···

--------------------
user = "Iñaki"
puts user
--------------------

Now run:

~# ruby1.8 script.rb
=> "Iñaki"

~# ruby1.9 script.rb
=> invalid multibyte char (US-ASCII)

I'm using the last 1.9 version: ruby-1.9.1-p129

How can it be possible? Of course, the file "script.rb" is encoded in UTF-8,
sure.

That is not the last, but it also occurs with 1.9.1-p243.

How about:

# encoding: utf-8
user = "Iñaki"
puts user

I confirm this script also fails with 1.9.1-p243 on Mac OS X 10.5.8.

That's pretty terrible. Can anyone explain what the problem is?

Yes, that works... but I cannot figure why is this required. I use a system
in UTF-8 so the file is encoded in UTF-8. Also Ruby1.9 seems to work in UTF-8
by default:

"abc".encoding
=> #<Encoding:UTF-8>

so...?

Thanks for your reply.

Thanks:

a US-ASCII Encoding, unless you say otherwise"
