Sorry, "compatibility" may not be valid wording. Now Linux is one of native application migration platform from *nix platform. Since SJIS charset does not have enough supported characters on Japanese environment. PCK and Cp943C charsets may be covered on this situation. ------------- PR: https://git.openjdk.org/jdk/pull/11908
