This example shows a compression algorithm which removes all extra bytes of Unicode text and returns an error if the extra byte is not 0.

You must thoroughly test the UDFs you develop for algorithmic compression. If the compression or decompression algorithm fails, compressed data may not be recoverable, or may be corrupted.
