编译时出错：用于编码 windows-1252 的不可映射字符 (0x90D)

Question

I get compile error when typing javac Main.java in terminal and the message i get is:

.\Constants.java:32: error: unmappable character (0x9D) for encoding windows-1252.

I know it caused by this bit of code:

public static final String[] UNICODE_TEXT = {
      "― ", // CELL_EMPTY
      "✗ ", // CELL_X
      "𝑂 ", // CELL_O
      "  ", // CELL_INVALID
  };

It is the "✗ " and the " " that causes this problem since they are special characters. I don't want to change the code since it was provided by the course. How can I compile this?

Do set your Java Encoding correctly by creating the environment variable called JAVA_TOOL_OPTIONS and set it to -Dfile.encoding=UTF8
