How to pass data from cmd.exe window?

Question

Command line

From the program (Frame 3.5 winforms) I call the batch file and read the result of the execution, as well as the error, if it happens.

var processInfo = new ProcessStartInfo("cmd.exe", "/c " + "c:/app/remote.bat");

 processInfo.RedirectStandardError = true;
 processInfo.RedirectStandardOutput = true;
 var process = Process.Start(processInfo);
 
 string             error = process.StandardError.ReadToEnd();

error I send the variable to the remote machine:

File.AppendAllText("\\remoteserver\\app\error.txt" ,  "ОШИБКA: " + error + Environment.NewLine, Encoding.UTF8);

On Win 10 - everything is beautiful, the error is readable (Cyrillic), I run it on WinXP:

ERROR: "uppdate
"

In the batch file, the encoding is UTF, in error.txt - too. Where else to dig?

Answer 1

You have utf8 in the sources, and in WinXP cp1251, for example, and in some places even cp866.
You need to specify the correct encoding.
