How to store file with unicode characters using paperclip - ruby-on-rails-3

Question

I'm using paperclip gem to process some images and store them to Amazon S3. Each image represents person's name. I want to add support for names with unicode characters as well, but I can't make it work because of paperclip fails to upload a file with unicode characters in its name.
I can't just change Ñ to N before uploading, because then I'll overwrite an image that was uploaded with letter N.
Eg.
Two users: NUÑO and NUNO. I can't just tell paperclip to upload NUÑO.jpg as NUNO.jpg because that will overwrite previous NUNO.jpg.
Here's my pretty much standard production/staging environment configuration:
config.paperclip_defaults = {
:storage => :s3,
:url => ':s3_domain_url',
:path => 'assets/:class/:id/:style.:extension',
:s3_credentials => {
:bucket => ENV['AWS_BUCKET'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY_ID']
}
}
And here's related class with image attachment:
class NameSpread < ActiveRecord::Base
(...)
has_attached_file :rendered_image,
default_url: lambda { |attach| attach.instance.processing_image },
path: lambda { |attach| attach.instance.save_path },
styles: { (..) },
processors: [ :name_spread_processor ],
default_style: :spread
(...)
end
Here's save_path method:
def save_path
if Rails.env.production? || Rails.env.staging?
"assets/:class/#{gender}/#{name}/:style.jpg"
else
"#{Rails.root}/public/assets/:class/#{gender}/#{name}/:style.jpg"
end
end
This is the part that gets messed up: #{name}
Any ideas?

After two days of debugging, I found the solution.
I updated from ruby 1.9.2 to 2.0.0 and now everything works...
