| * This code demonstrates how to use Unicode Variation Selectors to encode and decode hidden messages. | |
| * | |
| * It defines two functions: `encoder` to convert a string into a sequence of Unicode characters that | |
| * represent the bytes of the original string, and `decoder` to reverse this process and retrieve the | |
| * original string from the hidden Unicode characters. | |
| * | |
| * The `encoder` function takes a string, converts it to a buffer of bytes, and then maps each byte to | |
| * a corresponding Unicode character. If the byte value is 15 or less, it uses the range U+FE00 to U+FE0F; | |
| * if it's greater than 15, it uses the range U+E0100 to U+E01EF. |
