Hello everyone. I tried to build the ue5 editor via source code from github.
I followed the README and got some rare output errors which I didn’t know how to solve them. And the outputs are as followed.

4>Creating makefile for UnrealEditor (no existing makefile)
4>Creating makefile for UnrealHeaderTool (no existing makefile)

Do you guys meet the same errors?

Fix the error via modifying VCToolChain.cs Line 411.

			// Fix Incredibuild errors with helpers using heterogeneous character sets
			//if (Target.WindowsPlatform.Compiler.IsMSVC())
			//{
			//	Arguments.Add("/source-charset:utf-8");
			//	Arguments.Add("/execution-charset:utf-8");
			//}

Just comment these codes and I can successfully build.
