This is my interpretation of the Magic: The Gathering's language of Phyrexian. Most upper & lower case letters are represented ("i", "j", "I" and "J" are omitted.) All numbers are represented. The only puncuation represented are "comma", "period" and "vertical line".
Sempahore is a flag-based form of communication, used to visually communicate information over long distances.
Lower case lettes (NO CAPS LOCK REQUIRED) & the following special characters are used:
Period (.) = "Rest" in semaphore.
Pound Sign (#) = "Numbers". Since some letter symbols are also used as numbers, type in # before typing in numbers. Conversely, type "J" to indicate you're going back to letters.
Exclamation Point (!) = "Attention". Type !, when the message is important.
"X" = "Cancel". To nullify the previous message.
This is the Norse alphabet, known as Futhark (named after the first 6 letters of the Norse alphabet).
"A", "E", "N", "S" and "T" represent the compound letters, otherwise, NO CAPS REQUIRED! There's also numbers & a symbol for the SPACE.
Only people with OCD can read this encryption (supposedly), because of their unique awareness of complex patterns. Causes confusion in everyone else. NO CAPS REQUIRED, NO NUMBERS. Just basic puncuation.
This is my interpretation of Huttese, the language Jabba the Hutt speaks in Star Wars. NO CAPS LOCK REQUIRED! NO NUMBERS OR PUNCUATION.
