# Mourier Alphabet

## Mourier Encoder

 Version Original from 1971 (Only A-Z letters) 1.0 (from 2002, with digits, lowercase, etc.)

### What is the Mourier alphabet? (Definition)

The Mourier alphabet is a geometric alphabet defined by the danish designer Eric Mourier in 1971. It associates the latin letters with a symbol created from a 7x7 square (49 squares) composed only of lines which do not intersect and separated by a space of the same size.

### How to encrypt using Mourier alphabet?

In the original version of 1971 Mourier proposed a substitution of the letters A-Z by a Mourier square symbol according to the correspondence table:

Example: MOURIER is written as

The alphabet was then digitized in typeface in 2002 by Sébastien Hayez, and was enriched with ASCII characters.

A 2.0 version has been available since 2020 to adapt to Cyrillic characters.

dCode is intentionally limited to version 1.0 with uppercase letters A-Z, lowercase a-z, numbers 0-9 and the characters #, \$, &, * and /.

### How to decrypt Mourier alphabet?

The Mourier alphabet is a mono-alphabetic substitution (1 Mourier symbol = 1 plain letter or number character) so a replacement of the symbols makes it possible to find the plain message.

Example: is translated DCODE

### How to recognize a Mourier ciphertext? (Identification)

The Mourier alphabet is resolutely geometric with a fixed size of 7x7 small squares.

The assembly of characters can make one think of a labyrinth.
