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

Ruby
1

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.

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?

How about:

encoding: utf-8

user = “Iñaki”
puts user

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:

“The first is the main rule of source Encodings: source files receive
a US-ASCII Encoding, unless you say otherwise”
