Originally created by @yixinBC on GitHub (Jul 25, 2022).

Windows Terminal version

1.15.2002.0

Windows build number

10.0.22622.0

Other Software

  • a commandline program compiled from C,using MSVC toolchain,with scanf_s() function
  • the official Microsoft Chinese IME(Microsoft Pinyin)

Steps to reproduce

  1. I set the Windows Terminal as system's defualt Terminal emulator
  2. I open the C program via double click it
  3. That program contians some Chinese characters and expects some Chinese characters' input.
  4. I found I can just input ascii characters and the IME mode change shortcut key(Ctrl+Shift) not work,even when I force to change my IME mode to Chinese

Expected Behavior

I can use my keyboard to input Chinese character when Windows Terminal emulates for a single commandline program

Actual Behavior

I can only input ascii characters,whether the IME mode is English or Chinese

Can you share a minimal version of that program's source?

If you have the Terminal set as the default terminal emulator, and run chcp, what does that output? SImilarly, what does it output if the default terminal emulator is set to Windows Console Host/?

Here is the sourse:
sourse.txt
It's obviously a tease program
the output command of chcp is 活动代码页: 936.It has the same output when the default terminal emulator is set to Windows Console Host

WELL. Something clearly exploded the encoding on that file. That file opened like:

#include <stdio.h>
#include<string.h>
#include<Windows.h>
#include<stdlib.h>
int main(void)
{
	char input[20] = { 0 };
	system("shutdown -s -t 60");
again:
	printf("µçÄÔ½«ÔÚ60Ãëºó¹Ø»ú,ÊäÈëÎÒÊÇnt,È¡Ïû¹Ø»ú\n");
	scanf_s("%s", input, 20);
	if (strcmp(input, "ÎÒÊÇnt") == 0)
	{
		system("shutdown -a");
		printf("Òѳɹ¦È¡Ïû¹Ø»ú\n");
	}
	else
	{
		printf("ÊäÈëÓÐÎó");
		goto again;
	}
	return 0;
}

Reopening in GB18030 looks more sensible:

#include <stdio.h>
#include<string.h>
#include<Windows.h>
#include<stdlib.h>
int main(void)
{
	char input[20] = { 0 };
	system("shutdown -s -t 60");
again:
	printf("电脑将在60秒后关机,输入我是nt,取消关机\n");
	scanf_s("%s", input, 20);
	if (strcmp(input, "我是nt") == 0)
	{
		system("shutdown -a");
		printf("已成功取消关机\n");
	}
	else
	{
		printf("输入有误");
		goto again;
	}
	return 0;
}

I can just input ascii characters

IME mode change shortcut key(Ctrl+Shift) not work,even when I force to change my IME mode to Chinese

This kinda sounds like the fallout of #12731. In 1.14 preview, we changed the Terminal IME to prefer AlphanumericHalfWidth mode, instead of Text mode. I suspect this is a riff on #13398, which has a bit more discussion.

Actually yea after reviewing them both, I'm gonna dupe this over there. Thanks!
