title: special Chinese characters comparison
body: <p>. There are something misunderstanding when comparing two characters "李","李".</p>
  
  <pre><code>&gt;&gt;&gt; "李" == "李"
  False
  
  &gt;&gt;&gt; id("李") # fisrt one
  140041303457584
  
  &gt;&gt;&gt; id("李") # second one
  140041303457584
  </code></pre>
  
  <p>. The first character "李“ id is equal to the second "李" id, but when i try to compare their id to see what happen:</p>
  
  <pre><code>&gt;&gt;&gt; id("李") == id("李")
  False
  
  </code></pre>
  
  <p>. However, I tried to use chrome "Ctrl + F" that searching the first "李" and matched the second "李".</p>
  
  <p>. Does anyone know what happens? what should I do to fix this let the first "李" equal to the second "李"?</p>
