This font displays each character as a seven segment representation of the binary value of the character according to the GSM 7-bit alphabet. The commercial at (@) has been swapped with the space as I don't know how I could have a blank character that isn't space. I put the escape character in place of the reverse solidus (\), and I put the carriage return and line feed characters in the place of the left and right square brackets respectively, as these characters are not represented in fonts.
