Eclipse encoding

问题:

I set my eclipse default encoding by trying: Windows > Preferences > General > Content Types, set UTF-8 as the default encoding for all content types. Windows > Preferences > General > Workspaces, set "Text file encoding" to "Other : UTF-8".

Then we I import some projects, it always mess up some characters:

                    case 'a':
        case 'e':
        case 'i':
        case 'o':
        case 'u':
        case 'y':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
        case '�':
    }

What should I do? Any ideas?

Two things maybe happening:

1. Some projects (even folders and/or files) may have their own specific charset which could be different to the whole workspace-level charset preference. You could right-click on the specific file and do Properties -> Resource to check which text file encoding is really being used (Default computed or Other). As additional info, this Resource specific preferences are stored in the ./settings/org.eclipse.core.resources.prefs file of the project.

2. If the computed charset is UTF-8, the file you are viewing in the Java editor is not really coded in UTF-8. To verify that, you could check those characters in a hexadecimal editor, and use this useful UTF-8 table to compare the expected UTF=8 hex value in the table and the actual value the hex editor shows you it has.

Did you try to change the .java file encoding from Eclipse (right click on the .java file -> Properties -> Resource -> Text file encoding)?
