+ Functionality in this module generally assumes valid input and
+ does not necessarily fail on input that does not use a valid
+ encoding, but may instead very likely produce invalid output.
+ </p>
+ <p>
+ File operations used to accept filenames containing
+ null characters (integer value zero). This caused
+ the name to be truncated and in some cases arguments
+ to primitive operations to be mixed up. Filenames
+ containing null characters inside the filename
+ are now <em>rejected</em> and will cause primitive
+ file operations to 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.
