No text, but a visual code

[-JKP-]

The following symbols:  q  f  p  m  y   are demonstrably not to be identified with letters.

y is a very common symbol (abbreviation) in medieval texts. It is so common it is sometimes included as the last "letter" of the alphabet.

m is also very common. It is an abbreviation for -ris and its homonyms. It is also sometimes used as a paragraph-end marker.

Both are demonstrably identified with letters.
