-      <p>
-	Functionality in this module generally assumes valid input and
-	does not necessarily fail on input that does not use a valid
-	encoding. You can validate the encoding of a filename using
-	<seealso marker="stdlib:filename#validate/1">filename:validate/1</seealso>.
-      </p>
-      <p>
-	File operations used to accept filenames containing
-	null characters (integer value zero). This caused
-	the name to be truncated at the first null character.
-	Filenames containing null characters inside the filename
-	are now <em>rejected</em> and will cause primitive
-	file operations fail.
-      </p>
-    </note>
-    <warning><p>
-      Currently null characters at the end of the filename
-      will be accepted by primitive file operations. Such
-      filenames are however still documented as invalid. The
-      implementation will also change in the future and
-      reject such filenames.
