Convert ASCII hex codes to character in "mixed" string
<p>Is there a method, or a way to convert a string with a mix of characters and ASCII hex codes to a string of just characters?</p>

<p>e.g. if I give it the input <code>Hello\x26\x2347\x3bWorld</code> it will return <code>Hello/World</code>?</p>

<p>Thanks</p>
