title: Browser locale in japanese
body: <p>I am testing my web application and encountered an issue with japanese set as browser locale. Firefox has 'ja' as japanese locale while IE has both 'ja' and 'ja-JP' as locales for japanese. I want to know the difference between both locales - ja &amp; ja-JP . </p>
  
  <p>Issue I am facing now is - My web application loads .properties file based on the browser locale. It loads japanese properties file (Resources_ja_JP.properties) only when the browser locale is ja_JP. I want to know whether I can load ja_JP.properties file if the browser locale is 'ja'. If both are different, can someone point the difference between two?</p>
