For example, UTF-8 is based on 8-bit code units. Therefore, each character can be 8 bits (1 byte), 16 bits (2 bytes), 24 bits (3 bytes), or 32 bits (4 bytes). Likewise, UTF-16 is based on 16-bit code units. Therefore, each character can be 16 bits (2 bytes) or 32 bits (4 bytes).

WebThus, if you subtract 1 from a power of 2, its original bit goes to 0, and every bit below that goes to 1. In other words, no 1 bits overlap between a power of 2 and a power of 2 minus 1. This isn't true of other non-powers of 2. For example, 1001 minus 1 is 1000, which shares a 1 bit. Therefore, if you & a power of 2 with itself minus 1, you ...
