here language_controller.rb reads csv , converts json

class languagescontroller < applicationcontroller def availablelanguages = { :data => [] } @language = language.all.each |eachlanguage| availablelanguages[:data] << { :id => eachlanguage.id, :name => eachlanguage.languagename, :csv => [] } csv.foreach(eachlanguage.path) |row| availablelanguages[:data].each |single| single[:csv] << { :keycode => row[0], :unicode => row[1], :chakra => row[2] } end end @data = json.pretty_generate(availablelanguages[:data]) end render json: @data end

end

this adds additional backslash json so, \u091c becomes \u091c. here screenshot response in devtools corresponding rendered json.
