title: How to know what version of ICU comes with an OS?
body: <p>They say <a href="http://cldr.unicode.org/#TOC-Who-uses-CLDR-" rel="nofollow">here</a> that ICU is used on many platforms. But I can't find what version comes with OS X and Windows. In Linux I suppose a package-manager would tell me. </p>
  
  <p>UPDATE: Changed CLDR to ICU</p>
