This font is a facsimile of a substitution cipher from The Shadow #10, "Chain of Death." Letters are replaced by blocky symbols, which consist of pairs of rectangular shapes separated by a space. To encrypt a message, the symbols are connected together by their outer right and left edges. This gives the appearance of a much greater set of symbols than there actually are, and the spaces will confuse potential codebreakers. There are no numerals or punctuation. I included square brackets ("[" and "]") for two special symbols that are frequently used to begin and end sencryptions (you can type messages [like this]).
The symbols found in Gravity Falls: Journal 3, created by Bill Cipher.
Gravity Falls and everything to do with it are the property of Disney.
-- Spoilers --
Bill drew this language in secret messages throughout the Journal, as well as a wheel which can be used for decoding.
This is a randomised Pigpen Cipher (Also known as a Masonic cipher, Freemason's cipher, Napoleon cipher, and tic-tac-toe cipher)
Randomised to provide an extra layer of difficulty, and includes a variant on the grid symbolism to allow for some punctuation, numbers and basic maths.
(Designed this with DnD campaigns in mind)
This is a Rosicrucian Cipher made using a matrix of nine segments in the following order:
abc|def|ghi
jkl|mno|pqr
stu|vwx|y z
The symbol "_|" with a dot on the left is an "a", and the symbol "|_|" with a dot in the center is an "e".
There are also numbers in a similar grid:
1|2|3
4|5|6
7|8|9
Numbers do not have dots in their font.
The number "0" is represented by a box with a dot at the center top.
A period is represented by a box with a dot at the center bottom.
A comma is represented by a box with two dots, one above the other, in the center.
A question mark is represented by a box with one dot at the center top and two dots at the bottom.
Lower case is represented by solid dots.
Upper case is represented by hollow dots.
Alternating between upper and lower case may help confuse unwanted readers.
