title: How to decode Unicode escape sequences like "\u00ed" to proper UTF-8 encoded characters?
body: <p>Is there a function in PHP that can decode Unicode escape sequences like "<code>\u00ed</code>" to "<code>í</code>" and all other similar occurrences?</p>
  
  <p>I found similar question <a href="https://stackoverflow.com/questions/2045058/converting-these-types-of-unicode-to-utf8-in-php/2045105#2045105">here</a> but is doesn't seem to work.</p>
