char *ascii_ = \"中日         


        

Answer 1

You are omitting one step and therefore think the wrong way.

You have a C file on disk, containing bytes. You have a "ASCII" string and a wide string.

The ASCII string takes the bytes exactly like they are in line 1 and outputs them. This works as long as the encoding of the user's side is the same as the one on the programmer's side.

The wide string first decodes the given bytes into unicode codepoints and stored in the program- maybe this goes wrong on your side. On output they are encoded again according to the encoding on the user's side. This ensures that these characters are emitted as they are intended to, not as they are entered.

Either your compiler assumes the wrong encoding, or your output terminal is set up the wrong way.
