vs2017 uses cout garbled code, and uses printf to output normally
modify vs source files to gbk and utf, but still garbled
-sharpinclude<cstdio>
-sharpinclude<iostream>
int main() {
std::cout << "" << std::endl;
printf("\n");
system("pause");
return 0;
} 
has never encountered this situation. You debug it and have a look. Try changing the
character set setting to multiple characters.
General- > Character Set- > Use Multi-Byte Character Set. (VS2010)
still not used after trying
in CPP, characters other than ASCII characters are wide and need to be identified by L . The wide character stream has a specific output stream, which is std::wcout . Therefore, the correct output mode is std::wcout < < L "Hello" < < std::endl .
in addition, you need to refer to the concept of std::locale . std::locale represents a collection of settings for a region. locale document
each input and output stream can be bound to a std::locale . The default binding is std::locale ("C") . std::wcout.imbue ( locale ) is used here, and the region to be set is zh-cn . I did not find the relevant content. This region string may be related to the environment.
the final code is:
-sharpinclude <cstdio>
-sharpinclude <locale>
-sharpinclude <string>
-sharpinclude <iostream>
int main() {
auto old_locale = std::wcout.imbue(std::locale("zh-cn"));
std::wcout << L"" << std::endl;
std::cout << "old locale: " << old_locale.name() << std::endl;
auto new_locale = std::wcout.imbue(old_locale);
std::cout << "new locale: " << new_locale.name() << std::endl;
printf("\n");
system("pause");
}output is:
old locale: C
new locale: zh-cn
this part is complicated and I don't know much about it. I hope it will be helpful to you.
