The list of disallowed characters does not change depending on the underlying OS, it is a fixed list. From the documentation for <code>FileReference.download()</code> the list of disallowed characters is:

<pre><code>/\:*?"&lt;&gt;|%
</code></pre>

Edit: It looks like <code>@</code> isn't allowed either.

If you want to remove those characters from an arbitrary string you can do something like this:

<pre><code>var validFileName:String = invalidFileName.replace(/[\/\\:*?"&lt;&gt;|%@]/g, "");
</code></pre>

If you want to replace them with something else, then change the second parameter to <code>replace()</code>.

Edit: added the <code>@</code> character; escaped the <code>/</code> character.

The previous answer did not work for me. This is what did work (Using Flex 4.5):

<pre><code>public class FileNameSanitizer
{
public static function sanitize( fileName:String ):String
{
 var p:RegExp = /[:\/\\\*\?"&lt;&gt;\|%]/g;
 return fileName.replace( p, "" );
}
}
</code></pre>

And the testcase to prove it:

<pre><code>import flexunit.framework.TestCase;

public class FileNameSanitizerTest extends TestCase
{
 public function FileNameSanitizerTest()
 {
 }

 public function testSanitize():void
 {
 assertEquals( "bla", FileNameSanitizer.sanitize( "bla" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla/foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla\\foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla:foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla*foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla?foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla\"foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla&lt;foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla&gt;foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla|foo" ) );
 assertEquals( "blafoo", FileNameSanitizer.sanitize( "bla%foo" ) );

 assertEquals( "", FileNameSanitizer.sanitize( "/\\:*?\"&lt;&gt;|%" ) );
 }

}
</code></pre>

The use of FileReference has a constraint on valid characters. 
<code>Error: Error #2087: The FileReference.download() file name contains prohibited characters.</code> 
This is fine since I guess the restriction comes from the underlying file system anyway 
 
Is there such a things as a generic way to trim / replace all prohibited characters? 
 
For clarity I am after something like: 
<code>var dirty:String = "Eat this !@##$%%^&amp;&amp;*()\/";.txt</code> 
<code>var clean:String = dirty.replaceAllProhibitedCharacters();</code> 
 
I am not looking for OS specific regular expressions, but a cross platform solution.
