When developing C, C ++, Pro * C, and other programs on Linux or Unix systems, it is inevitable to use the gcc tool, A common Japanese Encoding System in Japanese is Shift-JIS encoding. However, when gcc is used for Shift-JIS encoding, some Chinese characters are garbled, why. In Shift-JIS encoding, two bytes are used for Chinese characters. When the second byte is 0x5c, garbled characters will occur when gcc is used for compilation. Generally, the following Chinese characters are incorrect. /X8

data. Text is always Unicode, represented by the STR type, and binary data is represented by the bytes type. Python 3 does not mix str and bytes in any implicit way, which makes the distinction between them particularly clear. You cannot stitch strings and byte packets, search for strings in a byte packet (or vice versa), or pass a string into a function with a byte packet (or vice versa).'
