Do the cryptic symbols/letters throughout the Bizenghast series mean anything?


In the Bizenghast manga series, the author uses some symbols over and over
again to represent writing or add to the style of the panels: [![A letter on a

There are other parts of the book that just represent writing as scribbles or
lines, so I wasn't sure if the symbols meant anything because they seem like
intentional words or writing.

**Do the symbols mean anything? Or are they just meant so that they don't have
to be translated if the book were translated to other languages for other
readers?**

If this is just a font or based on a font (like windgings or webdings), **does
anyone know what font it is?** The symbols don't seem to be random and they
could appear to spell words.
