    Carl, this is unfair!! You spoiled my April 1st joke in mid November!

    UTF-Morse - "Bringing Unicode in the telegraph age!"
        

    1. Unicode characters U+0020..U+007E are encoded according to the
    following table:

    U+007D --.-.- RIGHT CURLY BRACKET [1]
    U+007E --.--- TILDE [1]

    2. All other Unicode characters are encoded with one of seven
    multi-Morse schemes:

    Code range: Scheme
    ----------------- ------
    U+0000..U+0007 1
    U+0008..U+001F 2
    U+007F..U+01FF 3
    U+0200..U+0FFF 4
    U+1000..U+7FFF 5
    U+8000..U+3FFFF 6
    U+40000..U+10FFFF 7

    Each scheme uses a Morse sequence of the form ".-.yyy", possibly
    preceded by one or more Morse sequences in the form ".-.yyy":

    Scheme Bits (x: 0 or 1): UTF-Morse (y: "." if x is 0, "-" if x is 1):
    ------ --------------------
    ------------------------------------------------
    1 00000000000000000xxx .-.yyy
    2 00000000000000xxxxxx -..yyy .-.yyy
    3 00000000000xxxxxxxxx -..yyy -..yyy .-.yyy
    4 00000000xxxxxxxxxxxx -..yyy -..yyy -..yyy .-.yyy
    5 000000xxxxxxxxxxxxxx -..yyy -..yyy -..yyy -..yyy .-.yyy
    6 000xxxxxxxxxxxxxxxxx -..yyy -..yyy -..yyy -..yyy -..yyy .-.yyy
    7 xxxxxxxxxxxxxxxxxxxx -..yyy -..yyy -..yyy -..yyy -..yyy -..yyy
    .-.yyy

    3. Notes

    [1]: Some sequences are unique to UTF-Morse, and are unknown in
         traditional Morse code.

    [2]: Capital letters use the same code as small letter, preceded by
         sequence "..--" (which is unique to UTF-Morse).
