  See: http://rot8000.com/info http://rot8000.com/info It's essentially a Unicode version of the old "Rot 13" cypher. In Rot 13, you translate each letter 13 places down (as if on a code wheel), such that 'A' becomes 'N', 'B' becomes 'O', wrapping such that 'Z' becomes 'M', and so on. This version, instead of using the simple 'A=1...Z=26' number space, uses the Unicode range and rotates by 32,768 (0x8000).

    One key aspect you skipped over is it's self-reversible. 'A' becomes 'N', and applying it again 'N' becomes 'A'. "rot13 is reversible" -> "ebg13 vf erirefvoyr" -> "rot13 is reversible". "rot8000 is also reversible" -> "类籸籽籁簹簹簹 籲籼 籪籵籼籸 类籮籿籮类籼籲籫籵籮" -> "rot8000 is also reversible" Rot13 is English-alphabet only so it skips numbers, while rot8000 doesn't have this limitation because it uses the larger unicode set.
