title: How do I make the PHP similar_text() function work for Japanese Characters (Kanji, Katakana and Hiragana)?
body: <p>I'm wanting to use the similar_text() function provided by PHP for Japanese characters. But unfortunately it is giving the wrong answer. How can I make it work?</p>
  
  <p>For Example:
      <code>similar_text('土橋勇樹', '東日刷株式')</code>
  gives the output 3, but we can clearly see it should be 0</p>
