The message text file which I try to compile with windmc
When I save the message file in UTF-8 with BOM and try
compile the message text file with windmc message compiler,
I receive the following error:
C:/Users/danko/source/repos/PostInstallWizard $ cmake --build build

When I try to save Messages.mc in UTF-16LE without BOM, I have troubles with
editing it with most of text editors such as Microsoft Visual Studio one,
since some of them doesn't understand where is UTF-16LE without BOM.
Microsoft Visual Studio's MC (message compiler) does compile the Messages.mc
file saved in UTF-8 with BOM and recognizes Unicode properly.
I compile my application with w64devkit, my binutils version is 2.46.0:
C:/Users/danko/source/repos/PostInstallWizard $ windmc --version
GNU windmc (GNU Binutils) 2.46.0.20260210
