      Description

      https://mail.openjdk.java.net/pipermail/build-dev/2019-January/024581.html

      I tried to build OpenJDK on WSL (Windows 10 1809 + VS2017 (15.9.4) + Ubuntu 18.04 LTS).
      However, I saw some C4819 warnings as below:

      ```
      c:/OpenJDK/jdk/src/hotspot/share/compiler/methodMatcher.cpp(258): warning C4819: ファイルは、現在のコード ページ (0) で表示できない文字を含んでいます。データの損失を防ぐために、ファイルを Unicode 形式で保存してください。
      ```

      * The locale of my laptop is set to Japanese (CP932)

      I saw this warning at 2 files as below:

        - hotspot/share/code/codeHeapState.cpp
        - hotspot/share/compiler/methodMatcher.cpp

      We can see the problem with iconv:
        $ iconv -f US-ASCII -t UTF8 <file>
