title: Find Non-UTF8 Filenames on Linux File System
body: <p>I have a number of files hiding in my LANG=en_US:UTF-8 filesystem that have been uploaded with unrecognisable characters in their filename.</p>
  <p>I need to search the filesystem and return all filenames that have at least one character that is not in the standard range (a-zA-Z0-9 and .-_ etc.)</p>
  <p>I have been trying to following but no luck.</p>
  <pre><code>find . | egrep [^a-zA-Z0-9_\.\/\-\s]
  </code></pre>
  <p>I'm using Fedora Code 9.</p>
