title: How to decode base64 file path string in to apple script?
body: <p>I am writing an apple script which will take base64 string as argument. The base64 argument is file path. I have to open this file in specific application. 
  I need to decode this input argument to open the file.</p>
  
  <p>I tried the following code but the <strong>path separator (/) are decoded as %2F</strong>.</p>
  
  <pre><code>set decodedFilePath to base64decode(filePath)
  
  on base64decode(str)
      return do shell script "openssl enc -base64 -d &lt;&lt;END_OF_TEXT" &amp; str &amp; "END_OF_TEXT"
  end base64decode
  </code></pre>
  
  <p><strong>How can I decode the base64 file path string into AppleScript which will decode the file separator also?</strong></p>
