Thanks @magicus . The background is that we want to build CI/CD pipelines for Windows platforms to help the OpenJDK development. We already have enough Linux and MacOS pipelines but still not have one for Windows. So we just plan to setup some Windows pipelines to further improve OpenJDK product quality. But to my surprise, OpenJDK fails to build on our Windows platforms. You may suggest changing the locale settings. But many of our Apps don't allow us to changet it since we are non-English speaking country. It's unfortunate that OpenJDK can't build on our Windows platforms. It's not our goal to make CompileCommand work with non-ASCII chars. If it doesn't make anything worse, we can just remove the non-ASCII code to make it to be more portable. ------------- PR: https://git.openjdk.java.net/jdk/pull/5704
