What does the encoding of the created strings in C# depend on and how to find out?

Question

.NET

There is an application that calls a third-party process (console application).
This console application can output something in Cyrillic and wait for a response.
It outputs in UTF8 .
To give the right answer, you need to understand what the last output of the application.
On the computer I get a string, I compare it with a hardcode and everything is OK, all application lines are in UTF8.
On the server it turns out that the hardcoded string is encoded 1251 , although Encoding.Default == Encoding.UTF8.
How can I figure out what to encode a string from a third-party application into so that it can be compared with a string from the code?

Answer 1

Start -> "cmd" chcp - the actual current console encoding
Most likely it will be 866 ....
but nothing prevents you from doing chcp 1251 chcp 65001 or chcp 20880
