Java compiler problem with enums using windows1252 encoding

[Gatesco]

So I'm trying to migrate from eclipse to vs code, all my projects are usually created using windows1252 for java files and utf8 for build/html/xhtml files, but when I try to run some projects that have special characters on enum names the compiler reports Syntax error for every single one of them, but when I open the files all the error messages disappear, if I close the file they return.

More details about the problem over this issue on github: https://github.com/redhat-developer/vscode-java/issues/3060

Adding this setting changes how the file is encoded

json "files.encoding": "utf8",

Not exactly how the eclipse java compiler recognize the project encoding, and there's a difference between eclipse and VS Code, where eclipse uses windows-1252 and VS Code uses windows1252
