   @saintstack Hello and thank you for the review!
   
   Yes.  The two create the same output.  Since you pushed back on that (rightfully), I just wrote a small test suite to increase my confidence on that.  I generated many tens of millions of random byte patterns and compared the output of the two algorithms.  They came back identical every time.
   
   Just in case any inquiring minds would like to know, there is no longer an encoding required when generating the strings.  The JDK implementation specifically specifies that strings returned are `StandardCharsets.ISO_8859_1`.  This does not change anything because UTF8 and ISO_8859 overlap for the limited character set (64 characters) the encoding uses.
