title: Java Charset.forName("ASCII") or Charset.forName("US-ASCII")
body: <p>I was going through a code and came across the following line.</p>
  
  <pre><code>Charset.forName("ASCII")
  </code></pre>
  
  <p>But when I looked at the java <a href="http://docs.oracle.com/javase/7/docs/api/java/nio/charset/Charset.html" rel="nofollow noreferrer">documentation</a> it only has </p>
  
  <pre><code>US-ASCII    ISO-8859-1    UTF-8   UTF-16BE   UTF-16LE   UTF-16  
  </code></pre>
  
  <p>But the code works. Are 'ASCII' and 'US-ASCII' are synonyms in this context ? or is the code taking some default value since the 'ASCII' is not recognized ? 
  And how many bytes does 'ASCII' in this scenario represents a character ?</p>
