characters <-> digits

[eklem]

List / table for converting back and forth from plaintext to plaincode

Since it's all digital, there the logic of encrypting/decrypting are a little different. Less errors, more space etc.

• figures (digits) don't need to be written out three times.
• when marking a digit: , not shown character as a space, since numbers can be mixed with letters. This is not WW2 but kids language. This means it needs to be a 90 before each single figure/digit.
• If creating one for Norwegian, only 5 letters will fit on the first row, since the alphabet has three more letters (æ, ø and å)
• Longer one-time pads are okay as long as not stored on RFID-chips. Instead of 250, maybe 1000 or 1024?
• Skipping one number for both opening and closing parenthesis

plaincode conversion table for Norwegian

• 0 - CODE, use for i.e. emojis/smileys. If I need a codebook, it's for this
• 1,2,3,4 and 5 - most frequent letters, ertns
• 60-83 - ialodgkmvpfuhåbjøycæwxzq
• 84 - *
• 85 - @
• 86 - #
• 87 - +
• 88 - -
• 89 - /
• 90 - to mark a coming figure (digit)
• 91 - .
• 92 - :
• 93 - '

Not sure what to do with 81, 82, 83 and 84, maybe some of these could be good: &%*^§

Not sure of the frequency, but making one for each of North Sami, Lule Sami and South Sami:
