Localisation error: when Accept-Language header is Swedish (sv-SE), Chinese is shown

[aral]

When Accept-Language: sv-SE header is set, the localisation appears in Chinese:

Check if this is a greater issue with RoR AutoLocale implementation and fix at the right place.

Possible culprit:

In application_controller.rb:

class ApplicationController < ActionController::Base
  include HttpAcceptLanguage::AutoLocale

So here’s what I’ve found:

1. Tried to reproduce locally on OS-X running Ruby 2.2.3, Rails 4.2.1, i18n 0.7.0, http_accept_language 2.0.5 and couldn’t
2. On my OpenStack-based deployment environment where Boarding is running under Dokku, I can reproduce it everytime.

Tried:

1. To set default locale explicitly in config/application.rb:

config.i18n.default_locale = :en 

This seemed to help but I was randomly still getting other localisations (oddly, it seemed like I was getting some of the ones I’d explicitly visited earlier but with no discernible pattern between requests)

2. As a workaround, to disable localisation:

This isn’t an issue for us at the moment as the app is initially only available in English.

In /controllers/application_controller.rb:

class ApplicationController < ActionController::Base
  # include HttpAcceptLanguage::AutoLocale

I wonder if this is related to: iain/http_accept_language#50

(And, specifically, iain/http_accept_language@7319215)

Will review again once we have localised versions of the app itself.
