Ant Java构建:编译问题 - 将字符设置从ISO-8859-1更改为UTF-8

Question

有点新的字符集编码格式。我有一个蚂蚁构建脚本，该脚本以ISO-8859-1格式编译我的Java代码。它正常工作。

阅读了几篇文章后：如何在Java中的ISO-8859-1和UTF-8之间转换？

我已将字符集格式更改为UTF-8，从那以后开始编译问题。

抛出的错误是：

[javac] TestEncoding.java (at line 11)
[javac] case '?' :
[javac] ^^^^^^^^

我的构建脚本如下：

<javac compiler="org.eclipse.jdt.core.JDTCompilerAdapter"
destdir="bin" debug="true" deprecation="on" encoding="iso-8859-1"
source="1.6" target="1.6"
debuglevel="lines,source" failonerror="false" errorProperty="buildFailed">
<compilerarg line="-warn:+raw" />
<compilerarg line="-warn:-serial" />
<compilerarg line="-log source/testapp/compileLog.xml" />
<src path="testapp" />
<classpath refid="application.classpath" />
</javac>

我的班级之一，有问题的遵循代码：

public class TestEncoding {
public static final String filterAccent(String s) {
    StringBuffer sb = new StringBuffer();
    int n = s.length();
    for (int i = 0; i < n; i++) {
        char c = s.charAt(i);
        switch (c) {
        case 'á':
            sb.append("a");
            break;
        case 'à':
            sb.append("a");
            break;
        case 'ã':
            sb.append("a");
            break;
        case 'À':
            sb.append("A");
            break;
        case 'â':
            sb.append("a");
            break;
        case 'Â':
            sb.append("A");
            break;
        case 'ä':
            sb.append("a");
            break;
        case 'Ä':
            sb.append("A");
            break;
        case 'å':
            sb.append("a");
            break;
        case 'Å':
            sb.append("A");
            break;
        case 'ç':
            sb.append("c");
            break;
        case 'Ç':
            sb.append("C");
            break;
        case 'é':
            sb.append("e");
            break;
        case 'É':
            sb.append("E");
            break;
        case 'è':
            sb.append("e");
            break;
        case 'È':
            sb.append("E");
            break;
        case 'ê':
            sb.append("e");
            break;
        case 'Ê':
            sb.append("E");
            break;
        case 'ë':
            sb.append("e");
            break;
        case 'Ë':
            sb.append("E");
            break;
        case 'í':
            sb.append("i");
            break;
        case 'ì':
            sb.append("i");
            break;
        case 'ï':
            sb.append("i");
            break;
        case 'î':
            sb.append("i");
            break;
        case 'Ï':
            sb.append("I");
            break;
        default:
            sb.append(c);
            break;
        }
    }
    return sb.toString();
   }
}

我也试图将字符集更改为UTF-16，但是这一次它引发了不同的错误：

有人可以为此提供帮助吗？

谢谢，问候

我在编码级别上尝试了多件事。什么都没有。

最后，我尝试了Berger建议，将源代码编码格式更改为UTF-8，然后使用UTF-8构建一切都很好。我唯一必须保持关注的是对项目中使用的特殊字符。一旦更改了项目级别的编码，就会更改为特殊字符？符号。我需要转换所有这些？到实际特殊字符。这是我唯一需要花费的努力。对于开发人员而言，这可能是一个混乱的情况，但是由于这是开发人员的一次性活动/每个项目应该可以。

感谢Berger的建议。
