Corrected the version information (I had it wrong in front). Thanks to an alert reader for pointing it out. No substantive change. Enjoy.

| Cima's UTF-8 Magic Pocket Encoder - User's Manual |
| (vers. 1.2, 06 July 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. |
