YMMV, but to me a glyph is a glyph is a glyph.

The date is usually encoded as four digits.  On mine, for instance, it
reads 0112.  A 16-digit number, a four-digit number and a three-digit
number turns into a 23-digit number.  I personally chunk it into five
groups of four and one group of three.

c2l4 IHdv cmRz IGxv bmcu Cg==, as six chunks of four, took me about
fifteen minutes spread out over ninety minutes to memorize.  However, it
is not beyond the realm of possibility that I am a freak of nature.  :)
