WebThat would be the correct value if that 0xFF is just a bit pattern or if it represented an unsigned number (255). However, if that 8-bit pattern is being used to represent a signed value, we have a problem. 0xFF is -1. But 0x000000FF is 255. To get the correct 32-bit value, we need to sign extend the byte as it is loaded. We need to copy the ...

Web7. Unicode encodings ¶. 7.1. UTF-8 ¶. UTF-8 is a multibyte encoding able to encode the whole Unicode charset. An encoded character takes between 1 and 4 bytes. UTF-8 encoding supports longer byte sequences, up to 6 bytes, but the biggest code point of Unicode 6.0 (U+10FFFF) only takes 4 bytes. It is possible to be sure that a byte string is ...

A bit is the most basic unit and can be either 1 or 0. A byte is not just 8 values between 0 and 1, but 256 (2 8) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111.
