WebMay 9, 2014 · 1 byte is 8 bits, and can thus represent up to 256 (2^8) different values. For languages that require more possibilities than this, a simple 1 to 1 mapping can not be maintained, so more data is needed to store a character. Note that generally, most encodings use the first 7 bits (128 values) for ASCII characters. tatuaggi minimal https://dynamiccommunicationsolutions.com
