"IBM z/OS on mainframes used a character set called EBCDI"<p>"Each ASCII character is 8 bits wide, or one byte. The result of this means that if each bit is either a 1 or a 0 that there are only 128 possible combinations"<p>"it uses two chunks of 2 bytes, instead of 4-byte chunks in UTF-8"
does ascii have one of the bits reserved for parity check? This part confuses me:<p>"Each ASCII character is 8 bits wide, or one byte. The result of this means that if each bit is either a 1 or a 0 that there are only 128 possible combinations of ASCII characters."<p>If all 8 bits are used for data there should be 255 possible combinations.
