Workaround for Remarkable's deprecated I18n interpolation syntax

remarkable_i18n_fix.rb

# The I18n gem included in Rails 2.3.10 deprecates the {{key}} interpolation
# syntax in favor of %{key}, but Remarkable still uses the deprecated syntax.
# This is fixed in https://github.com/remarkable/remarkable/commit/23177b7ddd,
# but not yet released in a gem that's still compatible with Rails 2 and RSpec 1.3.

change_string_values_to_new_syntax = lambda do |key, value|
  case value
  when String then value.gsub!(I18n::Backend::Base::DEPRECATED_INTERPOLATION_SYNTAX_PATTERN, '%{\2}')
  when Hash   then value.each_pair(&change_string_values_to_new_syntax)
  end
end

I18n.backend.send(:translations)[:en][:remarkable].each_pair(&change_string_values_to_new_syntax)

Thank you!
