    | Cima's UTF-8 Magic Pocket Encoder - User's Manual |
    | (vers. 1.1, 30 June 2004, by Marco Cimarosti) |
    | |
    | - Left column: min and max Unicode scalar values: |
    | pick the row that applies to the code point you |
    | want to convert to UTF-8. Letters W..Z mark the |
    | hexadecimal digits that have to be processed. |
    | - Right column: hexadecimal to base-4 table. |
    | - Central columns: work area to compute each octet|
    | (1 to 4) that constitute UTF-8 octet sequences. |
    | Convert each digit marked by W..Z from hex. to |
    | b.-4. Write b.-4 digits on the dots placed under |
    | letters w..z (two b.-4 digits per hex. digit). |
    | Convert 2-digit base-4 number to hex. digits and |
    | write them on the dots on the line. That is your |
    | UTF-8 sequence in hex.! Exclamation marks show |
    | passages that may be skipped, either because the |
    | digit is hard-coded, or because it may be copied |
    | directly from the scalar value. |
