VS 2019 C++ 编译器无法编译某些字符串

Question

I have some strange and stupid situation. I have this part of code:

FString x = TEXT("ааааааа");//Russian language (line 54)
Caesar* ciph = new Caesar;// (line 55)

When I try to compile my project, I have such errors:

../Widget_Manager.cpp(54): error C2001: newline in constant

../Widget_Manager.cpp(55): error C2146: syntax error: missing ';' before identifier 'Caesar'

The most interesting thing (for me at least) that if I change 54 line on:

FString x = TEXT("абвгдеё");//Russian language (line 54)

or

FString x = TEXT("abcdefg");//English language (line 54)

or if I delete 1 'a' from Russian "ааааааа". It's compile.

Also I try hitting the keyboard in different ways, and I found other uncompiled letter combinations on Russian like: риорыва and нкешшур .

It's work similary without TEXT() macros.

As I understand Russian language contains, beginning with UTF-16. FStrigs is UTF-16. The only thing with which I can associate the behavior of the compiler is that (as far as I know) by default it works in the UTF-8 (whatever that means).

I would be glad if someone understand and can explain me what's going on.

I work in Visual Studio 2019, UE 4.26.1.

Afterword:

Problem was solved, but question: "Why some of Russian letter combination are compiled encoding while other combination are not compiled (on Cyrillic windows 1251)?" still remains.

Answer 1

If you need UTF-16 string laterals, you can use statements like this:

 char16_t str[] = u"Виян Лиже Первомай";

But, of course, it depends on implementation of FString class you use.

Answer 2

To solve compilation problem, I File -> Save as -> near save button arrow -> Save with encodig -> Choose UTF-8
