WebThese bits are numbered from 1 to n. An integer is stored in the cell in the following way: the least significant bit is stored in the first bit of the cell, the next significant bit is stored in the second bit, and so on; the most significant bit is stored in the n -th bit. WebTherefore, 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). All UTFs include the full Unicode character repertoire, or set of characters. Webchar char is the character type.
