Computer joke

Boiling and swallowing are generated by VC, which is the initialization operation of VC to memory in debugging mode. VC will initialize the newly allocated memory in the stack to 0xcc and the newly allocated memory in the heap to 0xcd. Repeatedly in GBK, 0xCCCC is hot, and 0xCDCD is a chariot.

Where are the handcuffs? In fact, in Unicode, if the code point is not defined, it will be filled with U+FFFD, expressed by UTF-8, and repeated twice with GBK is 0xEFBF (á) 0xBDEF (kg) 0xBFBD (copy copy).
