How to decode a string containing backslash-encoded Unicode characters?
<p>I have a string stored as <code>a</code>:</p>

<pre><code>a := `M\u00fcnchen`
fmt.Println(a)  // prints "M\u00fcnchen"
b := "M\u00fcnchen"
fmt.Println(b)  // prints "München"
</code></pre>

<p>Is there a way I can convert <code>a</code> into <code>b</code> ?</p>
